HI,
I am very new to COMSOL multiphysics.
I am using CFD> non-isothermal to simulation the room temperature.
After 300 iteration steps, I received the error mas at attched.
I shall be very thankful if anyone assist me.

Hi,

I am not expert on CFD module, but I guess in your equation you reported here the square root should be different than zero (either because you have a fraction in the sqrt, or because this equation is then used somewhere else). Therefore, try to add in your equation a very small value, let's say 1e-6, both at numerator and at the denominator, to avoid possible singularities.
