Are you using Scripts or Journal Files to do CFD simulations especially in Fluent or CFX? Why are you using or don't using it?

I am interested about the reasons and the simulation cases.

I use journal files for fluent in HPC especially for using UDF.

When I create case using desktop fluent with UDF and then try to run in HPC, it ended in error during partitioning. Since I had two mesh and 4 udfs, I think there might be difficult to modelling.

One more reason I go for journal file for the adjustment in solution controls in HPC. I initially start the simulation with reduced URF and first order schemes and after few iterations I gradually increase to the default URF and second order. If I create a case file in desktop PC and then run in HPC, it will be difficult to update once the solution is completed and wait for next queue. Hence I will write journal file in such a manner, after few iterations increase the URF and change to second order scheme.

fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.
