Good Morning Everyone, [COMSOL version: 5.2] My name is vaibhav and I am currently working on the micro-heater simulations for heating applications. In my simulation, power should be maintained at 15 mW. I am using Joule's Heating Module and under 'Eletric current' section, I am defining 'terminal' (type: Power) to fix power as 15 mW at one face. And, i am using 'ground' to ground the other face. It's a simple circuit with only resistance in between the two ends (or, faces; assume it as a solid block). But while defining 'terminal' as POWER, the software is aking for Initial Voltage (default: 0V) and Initial Current (default: 1mA). With these initial values, the simulation is giving error,
'Failed to find a solution. Segregated Step 1 Matrix has zero on diagonal. In Segregated Step 1: Returned solution is not converged. - Feature: Stationary Solver 1 (sol1/s1)'
I am unable to understand what values I should input in place of default values. And also it will be very helpful if you could explain why and how these values matter?
