Hey Hey

I had some problems with it as well.
Couple things that I made in order to fix it:

- on houdini.env file, write the following HOUDINI_OCL_DEVICETYPE=GPU

- Start the solver from frame 1

-I have a Nvidia card, go NvidiaControl panel>manage 3d settings> set OpenCL to video card.

Minimal solver don't keep previous frame, so use a cache to store the sim
