Checklist for HyperWorks CFD

ydigit

Some things to check for if HyperWorks CFD is very slow or showing segmentation faults randomly. 

1. Graphics driver version. Usually this is the biggest cause of graphics related issues

2. Delete HyperWorks settings file by using the utility in the folder 

C:\Program Files\Altair\2022\hwdesktop\utility\HWCleanup\

Note you will lose your preferences that you may have set. Close the apps before running it.  Start HyperWork-CFD and see if it runs. 

3, Check if only "HyperWorks" (i.e. not HyperWorks CFD) opens.  If yes, then contact support.
