I have been trying out 3D simulation cases with OpenFSI, especially the passing of rigid sphere over dam problem, and I end up encountering problems with the following line in the input file:
fix 2 all lb/fluid/viscous 1 1 0.1 10.0 setGamma 0.01 dx 1.0 dm 1.0 D3Q19 bc 1 1 1 1 1 1 inflow 0.0 0.1 0.0 printfluid 1000
Is there file by the name of fix_lb_fluid_viscous.cpp that is missing from this repository? If I use only lb/fluid then I am not able to set the bc and inflow parameters (see below line). Right now what works is:
fix 2 all lb/fluid 1 1 0.1 10.0 setGamma 0.01 dx 1.0 dm 1.0 D3Q19 printfluid 100
But this forces use of periodic 'p' boundary condition in both x and y direction and I cannot set the bc and inflow parameters leading to simulation break. Please help in overcoming this difficulty, especially with how to incorporate bc and inflow parameters and using "f" boundary condition (non-periodic) in x-direction. Any help is highly appreciated.
