Hello All,<\/p>\n

Whenever I try to run fluent simulation on my university HPC it fails to compile the UDF and refuse to run. I tried running without UDF and it worked perfectly but when I included the UDF I get the follow error message from the .out file.<\/p>\n

"faxxx\/Desktop\/3D_NC_v1\/3dsoln\/3dsolnv1_files\/dp0\/FFF\/Fluent\/libudf) is not compiled for parallel use on the current platform (lnamd64).<\/p>\n

Auto-compilation skipped. Could not find input files required for creating "C:\/Users\/faxxx\/Desktop\/3D_NC_v1\/3dsoln\/3dsolnv1_files\/dp0\/FFF\/Fluent\/libudf" library<\/p>\n

Error at host: The UDF library you are trying to load (C:\/Users\/faxxx\/Desktop\/3D_NC_v1\/3dsoln\/3dsolnv1_files\/dp0\/FFF\/Fluent\/libudf) is not compiled for parallel use on the current platform (lnamd64).<\/p>\n

Meanwhile, I have the UDF in the libudf folder. And the UDF has not issues because it works fine when i compile on my desktop. The issue only comes run I transfer the case, dat and all the other files to cluster. <\/p>\n

I have gone through some of the suggestions related to these issues on the forum. I converted the udf from dos2unix, so that’s not the issue. <\/p>\n

I have tried using expressions to define the density, viscosity, & mass diffusivity but it seems the option to do so is not available on version 21.1.<\/p>\n
