RE: Simulation Question

Hi,

I was simulating using C*S*T software and I encounter a message saying
"inhomogenous material at PML boundary detected"

Could I know what does that mean and how about do I go about solving it?

Thanks.
 

Re: RE: Simulation Question

Does this happen when you use Transient solver? If yes, you should use Frequency Domain solver.
 

Re: RE: Simulation Question

That means you have at least two different materials on the boundary, to which your boundary condition is open. I guess you might try to set "open" boundary to "open (add space)" from Solve->Boundary Condition. Or you could add your self some additional space to the model through Solve->Background Material-> [type the amount of additional space to the appropriate place (one of xmin,xmax,ymin, etc...)]

Regards,

Markus
