Time dependent adaptive mesh refinement output is on every mesh refinement -> large files

Hi,

I am evaluating the use of Comsol Plasma Module for the simulation of streamer propagation. The nature of the problem requires the use of adaptive mesh refinement in time. It seems that Comsol adaptive mesh refinement is doing a good job but it stores the solution in the beginning and at the end of every mesh refinement. In my case I do refinements quite often which results in huge file at the end. I do not need all these solutions (although they could be very useful for diagnostics). How can I tell Comsol not to store the solution at every mesh refinement but just in the specified by me times? The "times to store" option in the time dependent solver is set to "Specified times".

Thanks,
Stan
