Hello,

I have been running flow simulation on my model for about 3 months now on a Windows 64-bit PC (system info attached below). But for the past week, I have not been able to start Flow Simulation. Each time I click on the Wizard option, it hangs and I'm not able to proceed. I have to force close SolidWorks each time this happens. 

I have tried to run Flow Simulation on a simple tube but I can't get past the hang. One thing that worked for a while was using the Cleaning Utility to erase all simulation files but that has stopped working. Earlier, I did a full uninstall/reinstall and it worked but each time I close SolidWorks and open it back, I encounter the same issue where I'm not able to run Flow Simulation. More recently, I have done a full uninstall/reinstall and Flow Simulation wizard is nonresponsive. This is incredibly frustrating and I'm wondering if anyone has encountered a similar issue. Or if there's a solution out there.

Thanks!
