PC crashes during mass transport simulation

Hello all,

I have built a model with 57992 6-noded prismatic triangular elements, and 31901 nodes. When I am trying to simulate the mass transport my PC crashes.
Can any one help me? Is there any requirements on PC's RAM or CPU?
My PC's characteristics are Pentium 4 , 3.00 Ghz CPU, 1.00GB RAM

Thanks

Chrisoula,
the PC characteristics should be fine for this model. Please check all other settings.
