Remove FlIP particles from inside static object on first frame

Recommended Posts

Hello guys,

I'm pretty new to Houdini and I heard this is the best place on earth to get some help.  Please bear with me.  I have a closed static RBD object in a flip fluid tank (ocean FX).  The tank is filled with particles, and on frame 1, so is my static object which I don't want.  On frame 2, all the particles are pushed out of the static object and begin falling into the fluid affecting the simulation.  Is it possible to begin the simulation without having the particles inside the static object?

I hope I'm not being too vague,

Thanks

I have attached a simple example of how you can get rid of the points inside of an object by converting it to a vdb SDF and running a VEX function to test point positions against the SDF.

Thank you for the reply.  I managed to fluke the solution before I saw your reply.  I was using a beach tank which automatically set up collisions for my beach geo (which didn't have this problem), so I just imported my problem geo and merged it with the beach geo.  Problem solved! I recognise how easy this would be for you guys but Houdini is still alien for me right now.

 

Cheers
