Failiure on Simulation

Hello readers,

Next half year im on internship and using solidworks simulation a lot.

But... i've a major problem when making simulations.
When I add thermal loads the laptop is lagging enourmously!
Can't turn my model anymore becouse it instantly freezes and pops up the "program not working" wait or close.

Laptop i'am using:
Lenovo Y50
i7 4710HQ 2.5-3.4gHz 8 core threading
Nvidea GTX860 M 2GB
8 gb RAM

Specs must be enough!
Processor does not even reach 30% load.
Videocard sometimes 5% max.

Read something about cuda cores, GTX860M has cuda 1156 or 620

Have tried everything in options doesnt make a diffrence!

Does some one has an answer for this laggy problem

Thanks in advance,

Koen
