DC discharge - Undefined value found in the stiffness matrix

Hi everyone, I’m trying to solve a time-dependent study on a DC discharge 2d model. I inserted some fictitious boundaries in the geometry in order to facilitate the creation of a mapped mesh, but when...

Re: DC discharge - Undefined value found in the stiffness matrix

Maybe I solved the problem by marking the fictitious bondaries as mesh control edges.....

Chiara, When using the finite volume formulation, internal boundaries in the plasma region cause this error. The technique you mentioned is a good way to get around the problem. -- Luke Gritter AltaSim...
