ahvz is on a distinguished road
Hi to all,

I am trying to do transient analysis, the point that I can't understand is:

when I give the constant value of temperature ex. 10C as a convection boundary condition, why the temperature gradient is to high (25C to 29C) for sizing of 10sec and only 1 step with maximum iterations 25.

where is my mistake or misunderstanding ?

regards,
