To reseed a part, a part instance, or a region that has already been meshed, you must first delete the mesh in one of the following ways:
Before seeding, use the mesh deletion tools, described in “Deleting a mesh,” Section 17.14.2, to delete the mesh from the part, part instance, or region of interest.
Do not delete the mesh yourself; instead, attempt to seed the part, part instance, or region of interest. As soon as you select the parts or edges to seed, ABAQUS/CAE displays a window similar to the following:
You can avoid this warning message for the remainder of the current session by toggling on Automatically delete meshes whenever required. The next time you attempt to seed a part, part instance, or region that already contains a mesh, the mesh will be deleted immediately without any warning being displayed.
