I am trying to simulate degree of cure of epoxy in Comsol. I think my equations are correct but i keep on getting error message "Feature: Time-Dependent Solver 1 (sol1/t1) Failed to evaluate reaction forces at last time step. Attempt to evaluate nonintegral power of negative number. Function: ^ Failed to evaluate expression. "
Can anyone help me with the simulation. What could be the possible reason for this.
-Thanks Yeah.
