a short update: Still struggeling with strange physics in my result.
This simulation depicts the physical behaviour for 10 seconds. It looks like the whole model is kind of in a frozen state after the fibers have dived into the resin. So weird. Now I will reduce the viscosity of the resin by factor 10 and see if this changes anything. Further above I posted a simulation with inviscid multiphase model, this is still the only solution which physically makes sense. My conclusion from this is that my odd results should have something to do with viscosity..
