Hi everyone, I'm using Livelink(TM) for Matlab(R). When I tried to run the solution after inputting matrix to an electrostatic model's stationary solver, the error came out with "java.lang.NullPointerException" and the server flashes and disappeared. I've checked a few settings and found that it was probably about the multigrid preconditioner. I think the InputMatrix node cannot work well if the stationary solver uses multigrid preconditioner. But why? Can anyone tell me? How can I solve this problem?
The picture below is the example commands I use. Maybe help understand.
So much thanks
