Use the Mesh Refinement tool to create a regular orthogonal mesh.
Pattern based mesh refinement
Pre-requisite: The initial mesh must be a regular mapped quad mesh, not a free quad mesh.
1. | To open the Mesh Refinement tool, from the menu bar, click Mesh > Edit > Elements > Refine by Pattern. |
2. | Using the Select node: Nodes selector, select the center node to start the uniform mesh refinement. |
3. | For Select system, select a global or local system to be used for mesh propagation and box alignment directions. |
4. | Define the Refinement box, which determines the constant refinement zone. The elements inside this box should be the same size. |
a. | In the mesh size field, enter the fine mesh size. |
Note: | The size should be smaller than the initial mesh. |
b. | In the Length field, specify the length of the Refinement box. |
c. | To preview the box, click Review. |
5. | Define the Transition box. |
a. | In the Length field, specify the length of the Transition box. The mesh will be transitioned to match the initial mesh. |
Note: | The Transition box should enclose the Refinement box. The size of the Transition box determines how aggressive the transition will be. It is recommended that you limit the transition to 1 element connection 3 elements (1:3). |
b. | To preview the box, click Review. |
6. | Click Mesh. Attached 1D elements are refined. |
