hi guys,

i learned that one can compile solver in a applications/solvers folder, with wmake. and then use the compiled solvers in cases.
my question is, i was looking for the compiled exe file like icoFoam, but i only find the source code in .C.
but in the cavity tutorial i already used icofoam. could someone tell me how this work?

my second question, i did not find in bashrc file something about icoFoam, so how does this work, that when i type icoFoam, this solver is executed?

yo see i m a beginner, thanks for help.

executable file are placed in following addresse:
/opt/openfoam220/platforms/linuxGccDPOpt/bin

ofcourse i assumed you installed your OpenFOAM on opt folder

as you source your bashrc file during installation, you tell linux to read OpenFOAM bashrc which contains address of other folder paths, so it look up for example above address and returns your executable file

Hi Peter,

the .bashrc is a script which sets your environment variables where your system looks for the executables. To see where the icoFoam executable hides you can use the command

which icoFoam

Also the last line of a successful wmake-compilation gives you the full path to the produced executable.

Consider reading more about shell programming or read a bash tutorial.
