hexameshing of 2D elbow pipe

This tutorial demonstrates how to do the following:
• Block the geometry.
• Associate entities to the geometry.
• Move vertices onto the geometry.
• Apply mesh parameters.
• Generate the initial mesh.
• Refine the mesh.

Blocking Strategy

The blocking strategy for the 2D pipe geometry involves creating a T-shaped blocking and fitting it to the geometry. The 2D pipe geometry is equivalent to a T shape with the right side of the blocking crossbar bent upward to resemble the geometry. You will fit the T-shaped blocking to the geometry by creating associations between the edges of the blocks and the curves in the geometry, and then
moving the vertices of the blocks onto the corners of the geometry.

  1. Create the initial block.
  1. Split the initial block into sub-blocks.
    In this case, you will split the initial block using two vertical splits and one horizontal split.

3. Delete the unnecessary blocks.

Associate Entities to the Geometry

You will associate the edges of the blocking to the curves of the CAD geometry in this step. First select the
edges and then the curves to which you want to associate them.

Refine the Mesh

In this step, employ advanced edge meshing features to redistribute grid points to resolve the salient features of the flow.
