Tutorial 1: Getting Started
GridPro is an innovative, automatic grid generator which is easy to use when the user understands the basics of topology design. The technology is unlike any other grid generator on the market so we will begin our tutorial by starting out with a 2-D case that will emphasize the basic concepts and speed up the learning process. All of the concepts learned in 2-D will be used in 3-D grid generation that will be introduced in Part 2.

What you will create in Part 1:
Topology Design Intent
As you use GridPro to mesh more complex geometry, you will discover
that a mesh can be created in many ways. However, the reason
for using GridPro is to optimize the mesh on the area of most
importance, such as, the surface of the geometry. In this case the
mesh on the circle and four walls are of interest. Let’s mesh this
case with the same mesh density in another way by creating the
topology at the walls and assigning it’s wrap to the circle and compare
it to our original case.
What you will learn in Part 1:
- Starting a GridPro session
- Zooming-in on geometry in the work space
- Turning on and turning off the global axis system
- Sizing the Cut-Plane
- Creating basic topology
- Inserting topology edges
- Using groups to wrap the topology
- Assigning the topology to the surface of the geometry
- Creating and viewing mesh
What you will create in Part 2:
In most cases you will be working in 3-D to accurately simulate the flow around the model of interest. All of the concepts learned in 2- D can be directly applied to 3-D grid generation. In this case a grid of the geometry in Part I will be created in 3-D.
What you will learn in Part 2:
- Creating geometry in GridPro
- About various display modes
- Using a MACRO to automate topology and geometry creation
- Creating a wrap in 3D
- Doing and redoing topology commands
- Topology inheritance
- Snapping the geometry to the global axis
- Adding, clearing and subtracting topology from groups
- Introducing the grid viewer - how to make and manipulate grid view sheets
