My COMSOL simulation is not converging

Please login with a confirmed email address before reporting spam

I am trying to simulate moisture flux from a surface into air at a given tempertaure condition in a chamber. My simulation is working fine upto vapour pressure 50 kPa, unfortunately, when I am increasing my vapour pressure beyond 50 kPa, solution is not converging.

The error is coming as - Feature: Stationary Solver 1 (sol3/s1) Attempt to evaluate nonintegral power of negative number. - Function: ^ Failed to evaluate variable. - Variable: comp1.ht.phia

Please help me to figure out this problem.

Regards, Ashwani
