Hi all!!
I am trying to study the dielectric flow in an EDM process in which the adjacent electrode moves.I've attached the geometry as well as the mesh that i've create (Sorry for not using the the actual files as my PC dsnt have it rt nw. I work in my lab:P) .Although i don't have any interest in electrode yet i needed to mesh it and used its zone as Dynamic mesh. problems which i face..
1. Electrode walls are seperated into two (wall1 and wall1:001) Will it affect my result?. These are the walls of the mesh to which I've given dynamic motion
2.I gave UDF motion to both wall as well as wall:001. After a few times "negative volume is created"..
Please help me.its very urgent...
