Fluent 2022 comes with inbuilt compiler. this video is not necessary if using 2022 version. if using earlier version, when opening fluent in workbench, a setup window will open, in that make sure your udf file is present in the working directory. That is very important

[@CFD_Mechanic]

built in compiler works for you?

[@CFD_Mechanic]

inbuilt compiler does not work for me

[@vikkjayyak2642]

@@CFD_Mechanic yea it does. I compiled a rotating motion UDF and it compiled. Maybe you need to reinstall.

sir, i'm learning the udf, there are some questions confused me long time. hope you can give me some advices. the first question is the messaging passing type like PRF_CSEND and PRF_CRECV is block conmunicating or non-block conmunicating? the seccond question is the library of messaage passing in udf is same as mpi library?

[@CFD_Mechanic]

yes, just check from ansys website that which version is compatiable with your fluent version

Hey Ivica, I found an option for using in-built compiler near 'Build' in FLUENT R2020 R2. I haven't tried it, you can see the same in this video at 02:54. Hopefully, it is the same.
