Hey guys,
i am trying to simulate a FSI problem with ICFD solver in LS-Dyna, i.e. the process of a fiber bundle flowing through a nozzle. The simulation runs good until the contact between fiber(solid domain) and nozzle(fluid domain) appears. And LS-Dyna manager shows the error above. I think the error is maybe caused by the contact. But how can I apply the contact between a ICFD mesh and solid mesh? Can anybody help me out?

Hi @felix_fedi,
This has come up many times here. Have you tried looking in the search bar for "forrtl: severe (157)" and tried any of those solutions?
