Hi. This is my first post here. I'm generally okay finding solutions on my own, but I am stuck on this one.

I am working on a pyro and RBD sim where the explosion happens inside of a cabin that then blows out pieces. The pyro and RBD sims work fine by themselves, but when I make the cabin a static object, the pyro sim fails. I found a few tips online where I create the cabin using vdbfrompolygons and bring that into a static object in DOPs, then check invert sign. When I do that, it suppresses the explosion and it never fires off.


Anyhow, I am trying to get this to work and would appreciate some help. Also open to any other overall notes or tips once you explore the script. My experience in Houdini is about a year.

Thank you.

hi

I'am no Pyro expert at all
but I look'ed at your Scene and get it to work

I think you need a collisionsource
- you can create this with the shelf Tool - collisions - Deforming Objekt

change the Division Size
and also offset Surface




I increase the Substeps in Fire Sim to prevent the Smoke go throug the Objekt
- but still problems there


hope a pyro expert can help
