OpenFOAM preCICE

This is abstract.

preCICE is an open-source coupling library for partitioned multi-physics simulations, including, but not restricted to fluid-structure interaction and conjugate heat transfer simulations.

The adapter is built using GNU Make. The Makefile contains a few variables on top, which need to be adapted to your system:

1. CCX: Location of the original CalculiX solver (CCX) source code (“src” directory)
   • Example: $(HOME)/CalculiX/ccx_2.16/src
2. SPOOLES_INCLUDE: Include flags for SPOOLES
   • Example 1: SPOOLES_INCLUDE = -I/usr/include/spooles/ (installed)
   • Example 2: SPOOLES_INCLUDE = -I$(HOME)/SPOOLES.2.2/ (source)
3. SPOOLES_LIBS: Library flags for SPOOLES
   • Example 1: SPOOLES_LIBS = -lspooles (installed)
   • Example 2: SPOOLES_LIBS = $(HOME)/SPOOLES.2.2/spooles.a (source)
4. ARPACK_INCLUDE: Include flags for ARPACK
   • Example 1: ARPACK_INCLUDE = (installed, nothing needed)
   • Example 2: ARPACK_INCLUDE = -I$(HOME)/ARPACK (source)
5. ARPACK_LIBS: Library flags for ARPACK
   • Example 1: ARPACK_LIBS = -larpack -llapack -lblas (installed)
   • Example 2: ARPACK_LIBS = $(HOME)/ARPACK/libarpack_INTEL.a (source)
6. YAML_INCLUDE: Include flags for yaml-cpp
   • Example 1: YAML_INCLUDE = -I/usr/include/ (installed)
   • Example 2: YAML_INCLUDE = -I$(HOME)/yaml-cpp/include (source)
7. YAML_LIBS: Library flags for yaml-cpp
   • Example 1: YAML_LIBS = -lyaml-cpp (installed)
   • Example 2: YAML_LIBS = -L$(HOME)/yaml-cpp/build -lyaml-cpp (source)

You may also want to adjust the compiler FC from mpifort to mpif90 or to any other compiler your system uses.
