Hi,

I am struggling with imposing a condition on a dependent variable within the solution domain (not on the boundaries) during a transient solution.

More specifically, I'm using PDE solver to solve for three dependent variables, say (u,v,s), which all evolve in time and space. I need to impose a condition on one of the variables (say on s) in that if s<0.001 at some instanse in time within the solution domain set s==0.

I appreciate it if someone can comment on this.

Thanks,
Mehdi
