This page applies primarily to operational problems that might occur after SPACE GASS has been successfully installed. For installation problems, please refer instead to Titan Troubleshooting (if you have a Titan softlock system) or Hardware Lock Troubleshooting (if you have a hardware lock).
Note that these instructions apply to SPACE GASS 12.50 or later. If you have an earlier version of SPACE GASS then please Click Here for legacy troubleshooting advice.
The Windows 10 Creator update that started being rolled out in April 2017 has been found to cause problems in some parts of SPACE GASS 12.5. Reported effects of this Windows update include spurious errors and unpredictable behaviour in the portal frame builder (an “Invalid ridge position” error message), the shape builder (Tb getting the Tw value for I-shapes or Z shapes being drawn incorrectly) and the steel connection design module (random errors), however other unreported and potentially serious problems may also occur. The Windows 10 Creator update adversely affects the obfuscation used in SPACE GASS 12.5 and so a fix has been provided in v12.54.574 that uses a different obfuscation method. You can upgrade to get this fix by Clicking Here.
The same problem has been reported in SPACE GASS 12.5 with some versions of Windows 7 and Windows 8, and we suspect that an update of a particular Windows component is responsible for the changed behaviour. For this reason we recommend that you upgrade to v12.54.574 regardless of which version of Windows you have.
Do your diagrams look like this?

If so, it means that you haven't optimized SPACE GASS to use your graphics hardware properly. It also means that you haven't yet experienced the true power and silky smoothness of the SPACE GASS graphics. You should go to www.spacegass.com/hardware and follow the steps under "Optimize SPACE GASS To Use Your Hardware Correctly".
After correctly optimizing SPACE GASS for your hardware you will find that it not only looks better, but its graphics will also perform much faster and smoother, sometimes by a factor of 100 times or more!
Almost all of these types of errors are caused by an out-of-date graphics driver! Because SPACE GASS now takes full advantage of the parallel processing power of your graphics card, it relies on the OpenGL graphical software that comes with your graphics driver. If your graphics driver is out-of-date then unpredictable and unstable behaviour can result. Because of this, if you experience SPACE GASS crashing, a black background on the screen, blackened reports or unexplained error messages then you should update your graphics driver before trying anything else. This is very important!
Some examples of what you might experience with an out-of-date graphics driver are shown below:
SPACE GASS core crash
Black screen or report
OpenGL error message
The steps to solve these types of problems are as follows:
Note that you may also get this error when using the moving loads generator, portal frame builder, steel connection design module, RC beam module or RC column module. In all cases it is most likely due to an out-of-date graphics driver and you should follow the steps explained in "SPACE GASS Crashing, Black Backgrounds or Unexplained Error Messages" above.
If the problem persists after updating your graphics driver then you should try turning off hardware acceleration for graphical forms. You can do this by running SPACE GASS, going to "Settings => General Preferences" and unticking "Hardware accelerate graphical forms". This will result in slightly slower performance in the graphical forms and so it is important that you untick hardware acceleration only if you still have the problem after updating your graphics driver.
If you still experience the problem with hardware acceleration turned off then please generate a system information file, attach it to an email and send it to us at firstname.lastname@example.org along with a brief description of the problem. You can generate the system information file by running the SPACE GASS Utility 12.5 tool (via the Start menu => All apps => SPACE GASS 12.5 => SPACE GASS Utility 12.5), clicking the "Generate System Information File" button and then saving the SGSystemInfo.zip file to your desktop. Please be patient while the system information file is being generated as it may take a few minutes.
If you can't find the SPACE GASS Utility tool in your Start menu (or if you don't have a Start button) then just browse to your "C:\Program Files (x86)\SPACE GASS 12.5" folder, locate "SPACEGASS Utility Tool.exe" and double-click it.
A few people have reported that after updating their NVIDIA graphics driver they are getting jagged lines in SPACE GASS (ie. no anti-aliasing) or a black screen.
Jagged lines (no anti-aliasing)
This seems to be due to some NVIDIA settings becoming corrupted during the graphics driver update. You can fix it as follows:
If you get any unexplained errors related to not being able to connect to Titan when starting SPACE GASS or any sort of Fortran error when trying to analyse then it is probably due to your anti-virus software being a little bit over protective. The solution is to open your anti-virus software's control panel or settings and then add "c:\Program Files (x86)\SPACE GASS 12.5\sgwin.exe" as a trusted program.
If the screen text, side toolbar images and view selector are very small then you should turn off DPI awareness in SPACE GASS. You can do this by running SPACE GASS, going to "Settings => General Preferences" and unticking "DPI aware".
These errors can occur if you have SPACE GASS 12.50.439 or earlier and you are using the default "SG12Default" skin supplied with SPACE GASS. If this is the case then you should upgrade to the latest version of SPACE GASS by Clicking Here.
The error can also occur in SPACE GASS 12.50.440 or later with the default "SG12Default" skin if you have a high resolution monitor, Windows is set to magnify text and other items to greater than 100%, and DPI awareness is turned on in SPACE GASS. The obvious solution is to just change the skin by running SPACE GASS, going to "Settings => Color Preferences" and selecting a different skin.
Alternatively, you could reduce the Windows magnification back to 100% or turn off DPI awareness in SPACE GASS. You can change the magnification in Windows 10 by right-clicking on a blank space of your desktop, selecting "Display Settings" and then moving the slider to suit.
You can turn off DPI awareness by running SPACE GASS, going to "Settings => General Preferences" and unticking "DPI aware". Note that turning off DPI awareness in SPACE GASS may result in slightly less clear text in the SPACE GASS menus and buttons.
If SPACE GASS won't start and just seems to freeze when you try to run it, you should reset your configuration as follows:
Run Windows Task Manager by holding down Ctrl and Alt and then pressing Delete, followed by selecting Task Manager from the menu that appears.
Stop SPACE GASS by locating "SPACE GASS Core..." in the Task Manager list (it might be in the Apps (or Programs) section or the Background Processes section), selecting it and then clicking the "End Task" button. You can then close Task Manager.
Run the SPACE GASS Utility 12.5 tool (via the Start menu => All apps => SPACE GASS 12.5 => SPACE GASS Utility 12.5), click the "Reset Client Configuration" button (see below) and then confirm that you want to reset the configuration. Note that if you can't find the SPACE GASS Utility tool in your Start menu (or if you don't have a Start button) then just browse to your "C:\Program Files (x86)\SPACE GASS 12.5" folder, locate "SPACEGASS Utility Tool.exe" and double-click it.
SPACE GASS should then start normally.
If this doesn't fix the problem then it is most likely caused by your anti-virus software blocking access to some of the SPACE GASS configuration files that SPACE GASS needs to open at startup. This has been a reported problem after upgrading to Windows 10 when some versions of AVG and Symantec anti-virus software are installed, but it may not be restricted to just those two brands. You can test if it is an anti-virus problem by either re-starting your computer in safe mode or by uninstalling your anti-virus software (disabling it won't help), repeating steps 1 to 3 above and then trying to start SPACE GASS again.
For either of these errors the MS-Visual C++ 2015 redistributable package hasn't been installed correctly. You can get it from Microsoft by Clicking Here. When you get to the Microsoft website it will ask if you want to install either the x64 or x86 versions. You should download and install both.
This error has only been reported on a couple of older computers running Windows XP. If you are getting this error and do not wish to upgrade your hardware then you should use the Watcom solver and avoid the Paradise and Wavefront solvers.
If you are getting the error with a fairly modern computer running Windows 7 or 8 then please contact us at email@example.com for further investigation.
This error indicates that a file required for the 64-bit SPACE GASS analysis solver is missing from your system. You can get it from Microsoft by Clicking Here. When you get to the Microsoft website, click the red "Download" button and then follow the instructions to download and install the "Microsoft Visual C++ 2015 Redistributable Package (x64)". You should then be able to run the 64-bit SPACE GASS analysis solver.
SPACE GASS is having trouble running the 64-bit version of the solver. Try installing a file that enables 64-bit operations which may be missing from your system. You can get it from Microsoft by Clicking Here. When you get to the Microsoft website, click the red "Download" button and then follow the instructions to download and install the "Microsoft Visual C++ 2015 Redistributable Package (x64)".
If that doesn't fix it then browse to your SPACE GASS program folder (usually "C:\Program Files (x86)\SPACE GASS 12.5") and rename the "64" folder to "64a". This will disable the 64-bit solver and will force SPACE GASS to use the 32-bit solver. The 32-bit solver is slightly slower than the 64-bit solver and has a smaller problem size capacity, however the results and accuracy of the two solvers are identical. If the 32-bit solver hasn't been installed (ie. no "32" folder in the same location as the "64" folder) you can get it by Clicking Here.
This error may occur with time limited versions of SPACE GASS such as trial or student versions. Try right-clicking the SPACE GASS shortcut on your desktop and selecting "Run as Administrator". You should only have to do this once.
If the error persists then temporarily turn off your virus protection before trying SPACE GASS again. You can then turn your virus protection back on.
If all else fails you should try resetting the license by Clicking Here.
This error occurs if some components required by SPACE GASS have not been fully installed. Restarting your computer will usually fix the problem, but if the error persists then please Click Here to download the required components. After downloading you should double-click the downloaded file and then install both the x86 and x64 versions.
If you get this error when exporting a graphical image then you may need to install MS-Visual C++ 2012 redistributable package. You can get it from Microsoft by Clicking Here.
Click Here if your installed version of SPACE GASS is out of date and you wish to upgrade it to the latest version.
Click Here if you already have SPACE GASS installed and you wish to delete it and do a clean install. You may wish to try this if you are having problems that can't be resolved using the above suggestions or if you suspect that an upgrade was not entirely successful.
