Dear Radu,
Thanks a lot. I've managed to solve the problem. The issue was caused
by wmake, the build tool in OpenFOAM, which struggled with compiling Chrono
code directly within the OpenFOAM environment. To work around this, I now
compile the Chrono component into a .so file using CMake and wrapp all the
functionalities required by OpenFOAM in functions and used forward
declarations to avoid dependency conflicts. This setup prevents OpenFOAM
from trying to directly include headers from the Chrono libraries. This
method seems to resolve the issues.
Regards,
Jay
