[ANSYS Meshing] Material coalescense for geometry simplification (Heat Transfer)

dariohead · November 15, 2016, 08:36

Hi guys!

I'm trying to keep the temperature at a specific region of the interior of a device constant. It has a fan to regulate temperature and electronics and some structural elements surrounding the mentioned region.

The geometries of the electronics and elements are pretty complicated, and could be detrimental to meshing and computation processes.

The question is, would merging all similar materials into simple blocks of the same volume as the agreggate of all elements together affect the simulation notably?

The airflow of the heating/cooling fan is not directed to those elements, so maybe this simplification could model the phenomenom correctly.

Thanks in advance,
Dario

its always suggested to simplify your geometry.
Create small blocks representing different parts as its far easy to mesh and stabilize.
Make sure you give right boundary condition to those blocks and you shud get close enough result.
