failed to find a solution when coupling heat transfer with fluids dynamic!!

Please login with a confirmed email address before reporting spam

Hi everyone

I'm trying to model a transformer using multiphysic (thermal, fluid dynamic) modeling on Comsol.
when using only the thermal modeling, (only using heat transfer physics)
the program is running.but when adding the Fluid to couple the two phenomenon (using non isothermal flow) i got a divergence error
Failed to find a solution.
Maximum number of Newton iterations reached.
Returned solution has not converged.
Any ideas? Attached you will find my model. Thanks.
