My question is regarding the error with a particle tracing simulation in a magnetic field. Simulation is time dependent and has a step of 1e-6 seconds to 1 second, the mesh is around of 1 600 000 elements. The simulation gives me the error "Java heap space" at the end of computation and also in some trials with the same simulation also shows me the error mentioned an "Out of memory" upon particle tracing plot.

Thanks for your help

Thanks for reply
The java heap space problem is solved, but now the simulation reaches 100% of the linear solver and nothing happens, Comsol uses a core of four available cores, I give same time that Comsol takes to reach 100% complete linear solver and nothing happens, still in the same state.

best regards and thanks for your help
