Erasing a FEM Mesh—Topology Optimization
The Erase command is available after a mesh is generated.
To erase a mesh from the model, click Home > Mesh > Erase.
This only erases the mesh from memory. The Erase command does not erase saved mesh files.
For details about mesh, see the Creo Simulate help.
