"The calculation engine ran out of memory when attempting to run computations. You can attempt to avoid this problem by decreasing your simulation duration and/or increasing your output increment."
The first thing I would do is to see if you are using the 32-bit version of the program or the 64-bit version of it. If you are using the 32-bit version, I would try opening the 64-bit version. By default, the shortcut should use the 64-bit version if the program is installed on a 64-bit computer. You can check what version you are using by going to Help > About (program name). In the lower left of the dialog, you should see if you are using the 32-bit or 64-bit version. If you are using the 32-bit version, try computing the model with the 64-bit version. For SewerGEMS, you can find this by going to C:\Program Files (x86)\Bentley\SewerGEMS\x64\SewerGEMS.exe. For CivilStorm, you can find this by going to C:\Program Files (x86)\Bentley\CivilStorm\x64\CivilStorm.exe.
If you are using the 64-bit version, I would next try the two options suggested in the user notification. First, increase the output increment. This is done in the calculation options. Set the output increment to a higher value and see if that helps at all. If not, check the duration. If it is a long duration, try a smaller value.
If this doesn't work, you could also make sure you have the latest version of the software. The following link has information on how to access the latest version of the software: Downloading OpenFlows | Hydraulics and Hydrology software. You could also try to disassociate the model files from output and supporting files. This can be done by browsing to where the model is saved and creating a new folder. Then copy just the .stsw and .stsw.sqlite files to the new folder location.
