Energy residual not converge
Hi, I am trying run a transient CFD model of a junction box natural convection cooling over 50 mins. It runs fine at first several iterations but after a while the energy residual keeps increasing. (see the attached pic). The current time step is 10s and only small amount of mesh with skewness larger than 0.95 (less than 10) and orthogonal quality less than 0.1 (around 300), the total mesh number is about 10 millions. Could you please provide me some suggestions? Thanks!
