SACS 2024 - Joint Remeshing Utility


User can access this tool in Precede > JOINT > Connection > Re-Mesh Joint as specified below:

This tool allows user to perform more detailed analysis of hot spots and/or in convergence studies with different mesh sizes and element types. User can perform a box re-mesh of a previously meshed Joint. With that being said, the tool can only be used in conjunction with SACS Joint Mesher. For meshes containing SCF extraction hardedges, re-mesh retains the extraction joints and creates a new Post Input File.

Limitation: Currently re-mesh does not support meshes modified after creation.

Using the Tool

We use Sample 23 Joint Mesher for this example. After meshing the joint (2000) as below:

Go to Re-Mesh Joint:


1. Use Select Existing Mesh Restart File to load the JointMesh restart file which was created when the joint was meshed. The restart file contains a map of the finite element mesh and the original geometry of the meshed beam elements. Once the restart file is loaded, it selects the joint which was originally meshed and automatically sets the size of the bounding box to its extents. A box will appear as below:

2. Select the center of re-mesh box in Mesh Center Joint.

3. Use Toggle - Joint Selection / Bounded Element to visualize the elements which will be re-meshed.

4. Use Target Mesh Refinement Factor to either select the target mesh size or the refinement factor for the re-mesh.

5. Select the Target Mesh Type.

   

6. Optional: use Save Remesh Restart File to create a new JointMesh restart file. This is necessary if you plan to perform consecutive mesh refinements.

7,8. The size of the re-mesh box can be set using the X,Y,Z sliders. Use Bind Slider check box to adjust the size symmetrically (upper and lower bounds move together).

9. The orientation of the re-mesh box can be adjusted using ɸ1, ɸ2, ɸ3 angles with respect to the global coordinate system.

     

10. To adjust the face color and transparency, edge and line styles, and to display additional lines on the surface of the re-mesh box you can use the Bound Preview Settings.

  1. Face Color adjusts the color of the re-mesh box.
  2. Face Transparency adjusts the transparency of the re-mesh box.
  3. Edge Style adjusts the edge style of the re-mesh box.
  4. Lines on Faces controls which lines are draw on the re-mesh box.
  5. Line Style adjusts the line style of the re-mesh box.

   

Click on ReMesh to re-mesh the selected elements. Status dialog will show messages indicating different stages of re-mesh. Once the re-meshing is done, a text file containing a log of newly created Joints, elements (Plates and Shells) is displayed.
