I write a UDF file for dynamic mesh using DEFINE_GRID_MOTION Macro, and it works well when serial computing. But when I turn to parallel computing, it never works.
If I load case file in parallel computing used by serial computing directly, the Warning is "Auto-compilation skipped. Could not find "libudf" or input files for creating "libudf" library" and "incorrect grid motion UDF RBF::libudf on zone 6 (assuming no motion)".
If I compile and load the UDF file, then preview meh motion, it jammed and prompts "MPI Application rank 0 exited before MPI_Finalize() with status -1073740777".

Should I rewrite my UDF file and add some command like "#if !RP_HOST" "#endif" ? Or change environment settings?

The attachment is part of my UDF file.
