Is anybody having an issue in SW2015 Simulation Premium, where the solver disappears when a 2nd file is opened during the solving operation? With past versions, I have been able to start my solver for "Model 1", and open a 2nd file (Model 2) and alter geometry, examine, even start another run. However, with SW2015, immediately when I open that 2nd window with the 2nd model, the solver for the first model disappears and the result files show "Database not found". This has happened with linear, non-linear, and thermal runs, and I expect it would happen with the other types. Please advise if this is a problem others are seeing as well with 2015.

Thanks,
