How to run a transient simulation with udf in supercomputer?

      Hello,


      I would like to run a transient simulation with UDF in a supercomputer.


      Can someone give any guidelines for this?


      Thank you

      Which kind of guidance do you want? Running it on a supercomputer without knowing which scheduler and the underlying architecture are deployed.


      If you are running on such machines (which I made in the past) the first contact will be the admins of the machine. Regarding UDF's: I recommend here to launch the case with the UDF library loaded into it. This would avoid necessary compiling stage.

      Just to add, please make sure that UDF is parallelized. 


      Please try set up on simple case and make sure that its ok and then submit to supercomputer.

      Hello Just to add, If the UDF is compiled before submitting the case, make sure that your libudf folder has to be present in the same location where your case file is present. If you want to compile in HPC, you need add the compilation commands in the journal.
