Hello vganore,

I am trying to compile the udf of motion. But error pops up each time. It shows

Error: The UDF library you are trying to load (libudf) is not compiled for parallel use on the current platform (win64).nnThe system cannot find the file specified.

Fluent version is 18.2 and VS 2015.

Please help!

Are you able to compile other UDFs?

[Shuvadeep]

no

[DrAmine]

So you have compiler problem. Can you go to VS command prompt x86_x64 and launch Fluent from that prompt and compile a dummy udf.

[Shuvadeep]

Tried that also. Not working

[DrAmine]

Can you type cl to check?
Have you checked compiler threads under our installation subgroup?
