Hi everybody. This is my first post in this forum. I am working with COMSOL MULTIPHYSICS and I am trying to model a laboratory burner (Meker burner) heating a copper disc placed above the burner. I am modelling the burner as a boundary setting of heat flux entering the domain. I have obtained a solution for low values (1000-1800 W/m^2) but when I increase this value the model doesn´t converge and by my calculations the burner should give in order of 2exp6 W/m^2 (burner diameter 38 mm).(adsbygoogle = window.adsbygoogle || []).push({});

Could someone tell me if this value is correct and bring me some help in this issue.

Thanks anyway.

Martin.
