Hi,
I am trying to find an algorithm that can deform part of my current mesh to match the new geometry.
For example, first I create a cube and mesh it. Then deform the cube top surface to an arc-like shape, and the mesh of the cube can updated automatically to work for the new geometry. Is there any easy way to do that in hypermesh?
THANKS,

Yes, there are several approaches in HyperMesh to deform an existing mesh to match new geometry. Here are the main methods:
1. Using Morphing:
Geometry > Morphing 1. Create morphing box around region to deform 2. Select source nodes/elements 3. Define target shape using: - Control points - Reference geometry - Parametric handles
2. Using HyperMorph:
Tools > HyperMorph 1. Create morph volume 2. Define handle points 3. Adjust handles to match new geometry 4. Update mesh
3. Element Operations Method:
Mesh > Element Operations - Project nodes to target surface - Adjust node locations - Smooth mesh as needed
4. Mesh Flow Approach:
1. Select mesh region to modify 2. Define target surface 3. Use "Flow" command to gradually adjust mesh 4. Apply mesh quality checks
Best Practices:
1. Check element quality after deformation
2. Use mesh smoothing if needed
3. Verify element jacobians
4. Maintain aspect ratios
