Non-convergence in Hyperelastic Turbine Blade simulation under high Centrifugal Load

[SantoshKumarIITDELHI]

I am simulating a turbine blade using a Hyperelastic material model. The mesh consists of approximately 108,000 tetrahedral elements. The primary loading condition is a centrifugal force applied via a BodyForce kernel (or the CentrifugalBodyForce object). The simulation runs and converges successfully when the rotational velocity (centrifugal load) is low. However, when I increase the load to the target magnitude, the nonlinear solve fails to converge. I have attached the error file here.

hello

It looks to be converging, albeit too slow.
Can you increase the number of allowed nonlinear iterations?
nl_max_its, see this page for all the convergence parameters in the nonlinear solver parameters

if you want to converge it faster, you'll need to use a different preconditioning. I don't knnow what works best for hyperelastic problems

[GiudGiud]

also you may want to use less CPUs

  Num Local DOFs:          1425

this is a little low. We usually aim for 20k

Thanks.
