Simulation doesn't appear

Hi, my name is Ivan, I’m a new user of this forum.
I am making a simulation with Phoenix FD and when changed the Emitter Nodes the new one doesn’t work.
What can I do?

Hey,

Could it be that you use the sphere as emitter? If that is the case, you will need to either invert the normals of the capsule or you can specify the Capsule to be used as Confine geometry in the Grid rollout.
You can find more about the Confine geo here - Phoenix for 3ds Max

Yeah, that is what it was. Thank you Georgi!
