Good evening/afternoon,

Hi! This is my first post here, but I spent a lot of time reading this forum. First of all, thank you all for the help/advice in all these helpful posts. Now is my turn to throw the dice and get some personalized help if possible.

I am trying to add a new turbulence model to the DPMFoam solver. Specifically, I am trying to add the transitional k-omega SST LM model. To give some context:
  • Using OpenFOAM v2112 in a cluster (so no writing permissions in $FOAM_APPBIN)
  • Linux version Red Hat Enterprise Linux Server v7.9
  • compiling with gcc (Spack GCC) 10.3.0

The steps that I am following are the following:
Code:
$ mkdir ~/OpenFOAM/DPMFoamLM #Where my customized solver will be
$ cp -r /$FOAM_SOLVERS/lagrangian/DPMFoam/* ~/OpenFOAM/DPMFoamLM/ #Copying the solver to my custom solvers
$ export FOAM_USER_APPBIN=~/OpenFOAM #Pointing the variable to where I want my binaries from the solver
$ cd ~/OpenFOAM/DPMFoamLM
$ mv DPMFoam.C DPMFoamLM.C
After this I am modifying the files as following:
Code:
more /Make/files
DPMFoamLM.C

EXE = $(FOAM_USER_APPBIN)/DPMFoamLM
Then in the file DPMTurbulenceModels/DPMTurbulenceModels.C I am adding:
#include "kOmegaSSTLM.H"
makeRASModel(kOmegaSSTLM);

After these steps I do:
Code:
$ wclean
$ wmake libso
After that I got the following error:
Code:
/bin/ld: cannot open output file /storage/home/hcoda1/7/ibartol3/OpenFOAM/DPMFoamLM: Is a directory
collect2: error: ld returned 1 exit status
make: *** [/storage/home/hcoda1/7/ibartol3/OpenFOAM/DPMFoamLM] Error 1
What is curious is that when I modify icoFoam for example to add the diffusion of a scalar field it works well using a very similar workflow (just modifying what needs to be modified of course).

I also tried to do this locally in my local OpenFOAM compilation but compiling straight into $FOAM_APPBIN and it works...

Any help would be highly appreciated! And let me know if you would need further information, I am attaching the full log file just in case you want to read it.

Best,
Ignacio
