I use ODE and DAE to solve my issues. It's ok to store previous solution before I add Events under ODE and DAE interface.
Whenever I us Events, Comsol show a error message box:
" The following feature has encountered a problem:
Failed to find consistent initial values.
Singular matrix.
There are 1 void equations (empty rows in matrix) for the variable comp1.hpp.
and similarly for the degrees of freedom (empty columns in matrix).
Last time step is not converged.
- Feature: Time-Dependent Solver 1 (sol1/t1) "
I was definitely confused about this.
Can somebody explain to me and help me with a solution ?
Much appreciated !

Kind regards,
