Week 5.2 - Multi Level Meshing

Aim --> Multi-Level Meshing

1. Problem Description:

The Icepak model is given for this assignment. Open and unpack the given hanging_node.tzr model.

Without any modifications, the model results in about 700,000 elements. Note that this mesh count results from using the non-conformal meshing technique, which reduces mesh bleeding and mesh count. However, this mesh does not fully resolve the fine-level geometric features of the CAD objects. Using the multi-level meshing technique, you can reduce the mesh count and improve the mesh resolution on and around the CAD objects. This procedure starts with a coarse background mesh and resolves fine-level features through a series of successive mesh refinements. By using multi-level meshing and the uniform mesh parameters feature, you can reduce the mesh count to approximately 500,000 elements and improve mesh resolution.
