Hello everyone,

I want to to simulate the warming of PCM (phase change material). In approximation their phase change has constant volume. To attribute for the heat of fusion, I want to model a very high cp value, while using the regular cp value for the solid and fluid state. I found an already existing tabularThermophysicalPropertiesModel.

Following all the given steps, tutorials and the documentation I've been able to:

-create my own solver -> chtPCMFoam (equals chtMultiRegionFoam)
-compile the tabularThermophysicalPropertiesModel
-run the tutorial to check if the tabular model is installed correctly

Now I want to add the tabular model to my own solver, but it is giving me a hard time. As far as I understand it, I have to make changes to the Make/options file, and link my lnInclude and my shared libraries in there.

The libraries seem to work like this:

EXE_LIBS = \
    -L{$FOAM_USER_LIBBIN} \
    -L{$FOAM_USER_LIBBIN}/libTabularThermophysicalModels.so \
    -L{$FOAM_USER_LIBBIN}/libuserspecie.so

But the lnInclude part is returning an error all the time:

 EXE_INC = \
   -I$(HOME)/cfd/CFD/newSolver/tabulatedThermophysicalProperties-Feature_OF7/src/thermophysicalModels/specie/lnInclude \
   -I$(HOME)/cfd/CFD/newSolver/tabulatedThermophysicalProperties-Feature_OF7/src/thermophysicalModels/basis/lnInclude

wmakeLnIncludeAll: running wmakeLnInclude on dependent libraries:
    unknown option: '-I/home/cfd/CFD/newSolver/tabulatedThermophysicalProperties-Feature_OF7/src/thermophysicalModels/specie/lnInclude'

Usage: wmakeLnInclude [OPTION] dir

options:
  -update | -u      update
  -silent | -s      use 'silent' mode (do not echo command)
  -help   | -h      print the usage

    Link all the source files in the <dir> into <dir>/lnInclude

Note
    The '-u' option forces an update when the lnInclude directory already exists
    and changes the default linking from 'ln -s' to 'ln -sf'.

    wmakeLnInclude error: base directory \ does not exist
    unknown option: '-I/home/cfd/CFD/newSolver/tabulatedThermophysicalProperties-Feature_OF7/src/thermophysicalModels/basis/lnInclude'

I'm very thankful for any advice on how to do this the right way.

Did you solve this error.? I am facing the same problem.

Hey, to use wmake correctly, please check this page: https://cfd.direct/openfoam/user-gui...g-applications . You may for instance realize that the L prefix is to include an additional directory to the library lookup path and cant be used as shown in the initial post. It should be something like this:

EXE_LIBS = \
    -L<PATHTODIRCONTAININGLIBFILES> \
    -l<libname without "lib"in front and".so" at the end>

For the example shown in the first post:

EXE_LIBS = \
    -L$(FOAM_USER_LIBBIN) \
    -lTabularThermophysicalModels \
    -luserspecie

Hope this helps.

The problem is not with EXE_LIBS, The problem is with EXE_INC.

For example if I give

-I$/chemistryModel/lnInclude

it is not working with openfoam 6. But the same works with openfoam 2.4.x

Ok, the problem here is the use of $. In the Make/options $(<asd>) is used to access a predefined name. Type in your terminal

>echo $FOAM_SRC
>echo $FOAM_USER_LIBBIN

wmake accesses these variables through the following syntax: $(FOAM_SRC) and $(FOAM_USER_LIBBIN).
Your EXE_INC has to give the compiler a location to search for the different header files that you include in your application. The path has to be complete and here using predefined names can be helpful so that you don't have to type <ultralongpathtoOpenFOAM/OpenFOAM-<version>/src> all the time. But this can also look like this

EXE_INC = \
    -$(HOME)/myPrivateOpenFOAMLibraries/lib1/lnInclude
