Try to mesh a simple geometry (e.g. a cubic) in Workbench Mechanical on Windows, get a misleading error of “The mesh generation did not complete due to poor quality elements or incorrect input. Please try meshing with another mesh method or different mesh options”.

Solution # 2058100 is a good reference but finding a “clean” machine or reimaging OS may not be an immediate option for most customers. Some 3rd party software’s installation on Windows may place some old version Intel compiler runtime library files under C:Windowssystem32, and crash some ANSYS applications, including meshing in Workbench Mechanical and Mesh, Mechanical APDL, Explicit Dynamic, Fluent and other ANSYS solvers. For example, below files were found on two customers’ C:Windowssystem32 folder: 09/02/2010 08:20 PM 529,080 libiomp5md.dll 09/02/2010 08:16 PM 2,838,200 libmmd.dll The libiomp5md.dll is Intel OpenMP Runtime Library. And libmmd.dll is Math Library for Intel Complier. Both are required by AnsMeshingServer.exe. They are old dated, file size are much smaller than the below ones in “C:Program FilesANSYS Incv202tpIntelCompiler2019.3.203winx64″: 02/06/2019 08:38 AM 1,728,232 libiomp5md.dll 02/06/2019 08:38 AM 4,271,848 libmmd.dll Try to rename the 2 files by adding .old C:Windowssystem32, relaunch Workbench and/or affected ANSYS applications, it should turn to the correct libraries in ANSYS installation and fix the issue. Note: If above renaming affects 3rd party applications, copy them to the folder where 3rd party application executable is located and rename them back. Such Intel compiler runtime library files should not be placed in C:Windowssystem32, since different applications or same application but different versions may need different version run time libraries.
