please explain in more detail the procedure that makes VMD crash.
could it be, that you are simply running out of memory?

speed of VMD depends a lot on the CPU and graphics processor
(and driver).

you can load multiple volumetric data sets into the same molecule.

you can save generated volumetric data sets to .dx files.
VMD has a reader for that format.
