I am trying to simulate a the heat released in a quartz cuvette containing water and air, in which a laser is shined, heating nanoparticles, only if they are in the optical path of the laser beam. As a simple model, I substitute the laser beam in DEVICE with an uniform heat source. The quartz cuvette is surrounded by air.
qubet_modelling_2.ldev (6.1 MB)
When I run the simulation the error code 9002 appears and that the solver failed to converge after 40, 100 or 200 iterations (the values I tried).
What could be the source of this error? I would appreciate any help with this issue, thank you!
