Regarding Modelling using Plasma Module in COMSOL

Aishik123 · November 8, 2023, 07:11

Hi,

I am facing a "Divison by 0" error when hitting on compute button in plasma modeling in COMSOL 6.1. Can any one guide what could be the possible reason for this?

Hi, COMSOL is software program that using finite element analysis, it is common that it comes out of this error. Maybe you can try to simplify your input, for example

Original input: 4*3*2*1
change into: 24

Or you can try play with relative tolerance. I would say trial and error cannot be avoided, of cause with the condition that your model is correct.

Perhaps you can attach your comsol file here, for more discussion
