Variable for iteration count

I am performing a large number of sequential simulations via the matlab livelink. As far as I can tell, 'termination technique' has to be set to 'iterations or tolerance' or, in the case of an unconverged scenario, the whole run will fail. I would like to flag whether or not each simulation was terminated by iterations or by tolerance so I can discard those which were terminated by iterations. The intuitively obvious way of doing this is with a variable for iteration count. Is there such a variable and how can I access it? Thanks, Pete

Hi Pete

I don't think such a variable exists.

You can access the solver log using the API:

msg = model.sol('sol1').feature('s1').getString('message');

and check for any error or warning messages.

Hi Pete and Lars,

I was missing such a variable in some projects too. In some cases I implemented a counter using a global equation. However, this only worked in some cases and in other cases proved to be tricky. How about issuing a feature request to Comsol development?

Cheers Edgar
