I wrote an UDF for source term and it runs perfectly on my windows laptop. But when try to run on HPC it shows Error: chip-exec: function "cell_x_1source" not found.

Error: chip-exec: function "cell_x_2source" not found.

Error: chip-exec: function "cell_x_1source" not found.

  It only runs on 1 out 16 parallel nodes

Check the UDF Manual to see if the functions you're using need altering for parallel: that's the most common problem.

Thanks for the advice. I looked into the UDF manual, i compiled the UDF using journal file on HPC. It solved the problem.

Ah, in that case I suspect the problem was that the libudf wasn't compiled for parallel: that will have flagged an error earlier on but may have been missed as it tends not to crash the solver.
