For a week now i've been suffering from constant stress from CFX.nTo put it simply, CFX5 won't launch through Workbench 2020 R2 or throught the CFX5 console. This means neither CFX-Pre and the CFX-Solver will start. I've been using the license without problem since September 2020. Its due to expire on December 31st 2020.nThese problems came on suddenly. 16 solutions were succesfully solved but the last 6 with identical meshes would not solve. Giving me a 'not enough stack memory. I dont know what that means. Removing any mesh interfaces solved that issue.nThe new meshes had the same node count but without any interface boundaries. The next problem was that CFX-Pre could not start when started through Workbench. I could however start it through the CFX5 console and inject my mesh into it. Then export the CFX case so i could import it into workbench to solve. This no longer works. CFX-Pre will not start.nI am currently trying to solve a previous set-up file but now the CFX-Solver won't start. The entire system appears to be deteriorating around me and i need this software for my dissertation..nNo amount of uninstalling and reinstalling remidies this problem.nany ideas on a solution?.windows version :10.0.18363 Build 18363nCPU :AMD Ryzen 7 3700X 8-core @ 4.4GHz all coresnRAM :64GB @ 2400MHz, CL17nStorage, 3TB, 45% free spacen
December 1, 2020 at 3:06 pmANSYS_MMadoreAnsys EmployeeArray Can you try renaming C:\users\USERNAME\.cfx to .cfx.old and see if this clears up any of the behaviors? You can also try renaming %APPDATA%\Ansys\v202 to v202.old.nnThanks,nMattn
