I have installed openfoam 1.7.0 into ubuntu 12.04 LTS to perform LES. To allow timesteps to be determined by CFL number (maxCo), I modify the file:

/opt/openfoam170/applications/solvers/incompressible/pisoFoam/pisoFoam

to add the lines:

#include "readTimeControls.H"

below #include "readTimeControls.H"

#include "setDeltaT.H"

below #include "CourantNo.H"

And then compile pisoFoam with the following inputs in the terminal:

cd $FOAM_SOLVERS/incompressible/pisoFoam
sudo bash
wmake

However, error message comes:

g++ -m64 -Dlinux64 -DWM_DP -Wall -Wno-strict-aliasing -Wextra -Wno-unused-parameter -Wold-style-cast -Wnon-virtual-dtor -O3  -DNoRepository -ftemplate-depth-40 -I/opt/openfoam170/src/turbulenceModels/incompressible/turbulenceModel     -I/opt/openfoam170/src/transportModels     -I/opt/openfoam170/src/transportModels/incompressible/singlePhaseTransportModel     -I/opt/openfoam170/src/finiteVolume/lnInclude -IlnInclude -I. -I/opt/openfoam170/src/OpenFOAM/lnInclude -I/opt/openfoam170/src/OSspecific/POSIX/lnInclude   -fPIC Make/linux64GccDPOpt/pisoFoam.o -L/opt/openfoam170/lib/linux64GccDPOpt \

make: *** [/opt/openfoam170/applications/bin/linux64GccDPOpt/pisoFoam] Error 1

Any ideas as to what happened? I read some people suggesting a change in Gcc used in the compilation. Does it work? If yes, then how?

Thank you

The material here works for me:

http://www.cfd-online.com/Forums/openfoam-installation/78360-openfoam-1-7-x-fedora-13-a.html

In the file: wmake/rules/linux64Gcc/general, I do

 
PROJECT_LIBS = -l$(WM_PROJECT) -liberty -ldl $(FOAM_MPI_LIBBIN)/libPstream.so $(FOAM_LIBBIN)/libcompressibleTurbulenceModel.so

, to include both $(FOAM_MPI_LIBBIN)/libPstream.so and $(FOAM_LIBBIN)/libcompressibleTurbulenceModel.so, then in the EXE_LIBS option in the file ./Make/options in the solver directory, I add:
-lincompressibleTurbulenceModel

Then I can compile. For curiousity, I have a question. The drive for this change is for Fedora 13 (and in fact fixed as seen in their discussion), however, I need this change for installing openfoam-1.7.0 in ubuntu 12.04 LTS. Why?

After I compile pisoFoam with wmake and run, I found:

 
--> FOAM FATAL ERROR: 
Unknown turbulenceModel type RASModel

Valid turbulenceModel types:

1
(laminar)

I then follow http://www.cfd-online.com/Forums/ope...ype-error.html and http://www.openfoam.org/mantisbt/view.php?id=316#c751

I've changed the link lines in wmake/rules/linux64Gcc/c++ to

LINKLIBSO = $(CC) $(c++FLAGS) -shared -Xlinker --add-needed -Xlinker --no-as-needed 
LINKEXE = $(CC) $(c++FLAGS) -Xlinker --add-needed -Xlinker --no-as-needed

and changed the link lines in wmake/rules/linux64Gcc/c to

 
 
LINKLIBSO = $(CC) -shared -Xlinker --add-needed -Xlinker --no-as-needed 
LINKEXE = $(CC) -Xlinker --add-needed -Xlinker --no-as-needed

and then re-compile pisoFoam with wmake. Problem solved.

However, my way of changing pisoFoam is still problematic, such that the time step does not change correctly. I am still finding a way.
