Hi, i am simulating an enclosure with 2 fans, a few heat sources on a heat sink and a few components placed on the PCB. I did all the necessary boolean operations. I kept getting failed mesh due to overlapping connections. So to solve it, I added components to a new part and increased the tolerance of contacts.
In fluent, I used the transient solver with k-epsilon model with std function, Assigned source term to bodies, Mesh motion to the rotating domain, Pressure inlet with 60 deg C temperature and a pressure outlet, In mesh interfaces, I added coupled wall, SIMPLE model with 2nd order discretization The solution keeps diverging. I am unsure if it is because of the mesh overlapping connections or fluent settings. Any help would be great. Thanks. |
