Hello everyone,

It's probably ridiculous question, but as I'm very new to houdini, I can't figure out how to add the names of the fields that I've deleted by accident before running the simulation. Basically I want to run secondary elements sim and I can't because my surface and velocity fields dont have any name assigned to it.

Thanks a lot.

Use a Name SOP, and just give the primitive numbers the proper names:

0 -> surface
1 -> vel.x
2 -> vel.y
3 -> vel.z

thank you very much!
