Hello preCICE community,
I have a question regarding the restructured Fluid-Structure-Interaction tutorials.
In the “perpendicular flap” scenario the preCICE configuration file only contains one
fluid-mesh now, instead of the differentiation between faces and nodes before.
Looking at the OpenFoam configuration, displacements and forces are now both
related to the face centers.
Why is that the case now ? Is there anything I missed with the OpenFoam-Adapter ?
With this new configuration my fluid-mesh distorts unphysically. Before with the
differentiation in nodes and faces, everything worked fine. My solid participant takes
forces as input that are applied to the respective nodes of the mesh at the coupling
boundary and writes displacements back also from those nodes.
My question is: Why are only faces used in the new configuration and what
problem might occur that results in the crash by switching from the old config to the new one …
Maybe someone can give some input on this topic.
