I am doing research on stereo lithography process. Basically it's a process to solidify a liquid resin. I am doing process planning for this system, so I use MATLAB to run Comsol simulation several times to simulate the whole process. The problem right now is when I run the Matlab code, it gives me the error:
Running COMSOL Simulation (Next Layers Loop) for pixel #21 for curing time of 2 seconds for count# 3
Error using axisym_growth7 (line 61)
Java exception occurred:
Exception:
com.comsol.util.exceptions.FlException: The following feature has encountered a problem
(rethrown as com.comsol.util.exceptions.FlException)
(rethrown as com.comsol.util.exceptions.FlException)

Repeated error test failures. May have reached a singularity.

Last time step is not converged.
- Feature: Time-Dependent Solver 1 (sol3/t1)
However, if I manually run the simulation in COMSOL, it is working without any error. I am wandering if someone met this problem before? or who can give me some suggestion to overcome that problem?
Thanks in advance!

I have the same question. Do you have solved the question?
