Hi everyone

Iam trying to edit the compressibleInterfoam (Multiphase) solver to add time dependent acceleration to my case. On executing wmake i get the following error "fatal error: createAlphaFluxes.H: No such file or directory"

In order to check if the error is due to the editing done to the .c file, I tried compiling the compressibleInterFoam solver by changing its name to compressibleInterFoam_trial. I still get the same error.
Can someone help me in this regard.

Any inputs are highly apreciated.

Thank You

well, the error message says it can't find the file, so that is the issue. Even though you can see the file, it doesn't mean the compiler can (it needs to be told where it is).


So the first thing you need to do is to locate the createAlphaFluxes.H file. I assume it is not inside your workfolder (the one containing your actual *.C file(s) and the Make folder, the compiler searches here by default).


Once you have the file located there are two options: The easy one is to simply copy the file into your workfolder so the compiler can find it here (this is, however, not good programming practice), the second option (and preferred one) is to include the path to the file during compilation. For that you have to add the folder location to your EXE_INC variable in the options file within the Make folder, which might look something like

Code:
EXE_INC = \ 
  -I$(LIB_SRC)/finiteVolume/lnInclude
To add yours, add your path below the last line and add a \ at the end of the previous line. There is one file called createAlphaFluxes.H in $(FOAM_APP)/solvers/multiphase/VoF, so assuming this is the file you want just add that to your path and it would become

Code:
EXE_INC = \ 

  -I$(LIB_SRC)/finiteVolume/lnInclude \
  -I$(FOAM_APP)/solvers/multiphase/VoF
