Tutorial 3: Creating a Grid Between Two Intersecting Surfaces

photo

Creating an internal mesh on a surface intersecting another surface is important for design analysis. At times, only one part of the geometry will be analyzed while the other parts will not be meshed. In Part I we will learn how to make an internal mesh on a 2D surface while the curvature of the intersecting surface will be used as a boundary. In Part II, we will mesh a similar geometry in 3D and will introduce the function of the Cut- Plane which will be extremely useful in designing topology for complex shapes.

What you will create in Part 1:

We will make an internal mesh on a 2D surface while the curvature of the intersecting surface will be used as a boundary. GridPro allows the user to automatically load the grid and change its density while it is converging to equilibrium. This interactive tool is useful in inspecting the grid quality and making necessary changes quickly.

The mesh along the length is course. This problem can be corrected interactively by going back to the Topology Builder and increasing the density along the length. Change the density to 28 and select gridden from the topo pull-down menu.

What you will create in Part 2:

One of the most important aspects of using GridPro is in creating topology for complex geometries. Locating the corners and edges of the topology, particularly in 3D, can be time consuming and tedious without a tool that can automate the process. For this reason, the Cut-Plane in GridPro allows the user to speed up topology creation while increasing the grid generation efficiency. In this section, we will learn how to use the Cut-Plane and how to better visualize our mesh by using grid trimming commands. A brief example on how to use GridPro for CFD parametric design analysis will also be covered.
