Hi there,

I am trying to create a model that is similar to the cold water glass model found within the comsol model library. However, I want to have a temperature governed by a step function at the bottom (which I have) and a cold temperature at the top that I just define in the initial values.

However, when I try to compute the model, an error appears that says that the time-dep solution is not converging, could I get some help with this please!

Thanks

Ross

Exact error:

Nonlinear solver did not converge
Time=(arbitrary time)
Last time step is not converged
-FeatureTime-Dep Solver 1 (Sol1/t1)
- Error: Nonlinear ssolver did not converge


Thanks

Same results...Did you figure a solution?

Hi there,

I am trying to create a model similar to the cold water glass model found within the comsol model library. However, I would like to change the level of water in the glass, not full.

Help me to solve this problem?
Thanks
