1. Select the Mesh Module
2. Select Seed > Edge By Number
3. Select the square at the end of the block by clicking anywhere inside the square. Then enter the number of elements on each side you want (in this example four) and press enter or return.
4. Select Seed > Edge Biased. Then select on of the long edges near the end you want to have a denser mesh and click on Done at the bottom right of the window.
5. Enter a number for the bias ratio (in this example five). The bias ratio is the difference between the length between nodes at either end of the edge. So a bias ratio of five means that the mesh at the dense end will have element lengths one fifth (20%, 1/5) of that at the coarse end. Press enter and then enter the number of elements along the edge (in this example six). Then repeat this for all of the long edges (the other three edges) because any edge that does not have edge bias seeding will not create edge bias element lengths.
6. Select Mesh > Controls
7. Select Hex and Structured. The bar should appear green. The color that the part is in the mesh module refers to the type of elements.
8. Select Mesh > Part. The at the bottom of the window select the Yes box to mesh the part.
You are done!
