I am using Maxwell 2D to analyze a transformer for transient and magnetostatic solvers. When I click analyze all, the simulation is completed  suddenly (about in 4 or 5 second) but there is no error, no solution and result. In older simulations, it was analyzed longer and correctly. But, later this problem occured I tried to reset up the solution setup but it didnt work. What should ı do to be able to fix this .
