Hi everybody,
We are doing a project in model a liquid based thyristor cooling for this we have many channels of 0.5mm in thickness both solid fins and channel for flow, the problem is we cant mesh these small sizes with unstructured mesh and we also have problem in heat transfer that is ,Do we have to face connect for each channel and fin? thanks in advace

Hi!!

I don't really get your geometry...

But one thing, I can tell you: your geometry has to be consistent. That means, the the fluid areas have to be connected.

If the geometry is to complicated, you might divide your model into several sub-models (if there is no (or no big) coupling between them).

You can take the results from one channel simulation as a BC for the other parts simulation...

Best wishes
Ralf
