In this tutorial, the meshing process for an electronics cooling geometry through the conjugate heat transfer (CHT) technique is carried out, using the “Hex-dominant parametric” approach. The “Hex-dominant parametric” (only for CFD) is the semi-automatic meshing option that uses hexahedral cells and allows full flexibility in meshing parameters with all type of refinements options. The objective is to get a high-quality mesh with sufficient resolution to capture key features in the model.
This tutorial will highlight some essential points of the meshing process that help users achieve better simulation results.

Next, start with the Background Mesh Box, under Geometry Primitives. Here we can specify the extents of the box for the base mesh. It is suggested to maintain the automatic bounding box generated when a geometry is imported, since this is an important factor when it comes to splitting the different faces. The following Background Mesh Box and Material Point settings can be left as default for any other simulations you want to perform using conjugate heat transfer problem.
