Hi,
We are trying to reproduce a benchmark of FSI (Proposal for numerical benchmarking of fluid-structure interaction between an elastic object and laminar incompressible flow. S. Turek and J. Hron), our goal is to continue later with non-elastic material models (mfront) and non-laminar fluids, our goal is to simulate certain phenomena of human biology. For this reason we execute alternatively the Open Foam (fluid) and the code aster (solid) where the geometry evolves. We have different results from the bibliography and a doubt has arisen.
For each iterate (t_n), with the fluid calculation finished we resume the code aster calculation with a REUSE of the previous calculation with a DYNA_NON_LINE. We apply the force to the surface (which comes from the fluid) with a FORCE_FACE of the AFFE_CHAR_MECA. For this reason we apply the force to the operator with the SUIV option and we want to know if the force is applied on the initial reference state (t_0) or on the surface deformed by each invocation of DYNA_NON_LINE (t_n).
Best
Gerard
