Hi,

I am trying to model penetration depth of an array of microneedles in the skin. The microneedles are cone shape where I used copy and union to build the geometery. I used solid mechanics interface with linear elastic material analyser. I ran the model and it took about 24 hours to run, and I recieved the following errors. I check with all parameters and really don't know where is the problem:

Failed to find a solution. The relative residual (1.3e+02) is greater than the relative tolerance. There was a warning message from the linear solver. Iterative refinement triggered. Returned solution is not converged. Not all parameter steps returned.

I really appreciate if you could give me a suggestion in this regards.

Thank you,

Mitra
