hi,
i got a problem about MHD (magneto-hydraulic) simulation.The fluid is driven by a high frequency magnetic field and free deformation occurs hopefully.
The fluid deformation occurred at a relative low frequency ,like 100Hz , however,it does not work at high frequency,like 50kHz.
I guess it is because that the LORENTZ force is much big so that the mesh is inverted WHICH CAUSE THE CONVERGENCE PROBLEM. And i tried to use the automatic remeshing ,but it seems that it does not work at frequency-transient solver.Could anyone help me fix this issue?

Hi Li,
Can you attach your model to see what is wrong?
I think that automatic remeshing works in Frequency-transient simulations
