Hi

I am trying to simulate an Electrostatic Precipitator using a 2D Axisymmetric model. For the particle tracing and multiphysics coupling I have been following the modelling steps given by https://www.comsol.com/model/electrostatic-precipitator-71361.

The error I get is the following when I try to compute the particle tracing: There are 1450 equations giving NaN/Inf in the matrix rows for the variable comp1.fpt.cacc1.Za.

I belive the problem has to do with the Accumulated Charge Number but I can´t seem to figure out a solution. Any tips?

I have attached the model file

Thanks,

Jonas
