Hi everyone,
I am currently implementing a custom viscosity model, but when I try to compile it I receive the following error message

Make/linux64GccDPInt32Opt/options:55: *** recipe commences before first target.  Stop.
Make/linux64GccDPInt32Opt/options:55: *** recipe commences before first target.  Stop.
wmake error: file 'Make/linux64GccDPInt32Opt/sourceFiles' could not be created in /home/raoul/OpenFOAM/raoul-8/src/transportModels/incompressible/viscosityModels/customLaw

The files that I am working on are in the directory $WM_PROJECT_USER_DIR/src/transportModels/incompressible/viscosityModels/customLaw

while this is the customLaw/Make/files code

customLaw.C

LIB = $(FOAM_USER_LIBBIN)/libcustomLaw

and this is the customLaw/Make/options code

EXE_INC = \

	-I$(LIB_SRC)/transportModels/lnInclude \
	-I$(LIB_SRC)/finiteVolume/lnInclude

LIB_LIBS = \
	
	-lfiniteVolume

The previous code source comes from this presentation ( http://www.tfd.chalmers.se/~hani/kur...esentation.pdf page 11) that I slightly adapted to match with the directories of the OpenFoam installation folder. Being quite inexperienced I am struggling to find the error in my code (I assume it is in the options file but I might be wrong).

Thank you in advance.

Solved.

I deleted the directory that was created in the Make directory from the previous failed compilation. Compiled again and it worked. No idea why it worked tho.

Dear Raul,

I am trying to simulate rising bubble in a solution that its density, viscosity nad surface tension are chaning with the concentration of solvent. I am using interFoam and I would like to implement my own correlations for calculating density, viscosity and surfance tension. I am new in OpenFoam and I am looking for a tutorial or any guidance to start it. Could you please help me or share any tutorial if you have for this problem?

Thanks and best regards,
Sadra
