Hi all,
I am learning houdini right now and I first want to learn grain sims. I get good result at low res but when cranking up the res, it always end up exploding at some point. Could anyone give any tip on how to prevent grain sims to explode?
also…
Is there a way to restart a grain sim from where it was after stoping it?

Rohan Dalvi did a nice intro to grains

Try increasing the number of constraint interactions on your grain solver. Also, don't over crank any of the force weights (stress, clumping, etc) past 1.
To restart the sim, you need to cache and save the sim. Cache is on by default but you'll have to set up saving it out using the Output node. The help files cover this pretty well.
Good luck. Kevin
