• particle tracking problem

    Hi!

    I tried particle tracking in the unsteady condition. But the warning window popped up with the following message.

    "insufficient memory available A block of 602081 Kbytes could not be allocated Sorry."

    The number of  total element is 73600. It this problem concerned with my computer memory? Should I add the memory in my PC  though it already has 2Gbyte memory? And if I have to, how much? Does time step size in my model also matter?
