How can I prevent ANSYS Mechanical from renumbering cell zones/walls after mesh refinement, thereby ensuring my journal file remains compatible?

 ANSYS Mechanical renumbering cell zones/walls after mesh refinement is a common issue when dealing with journal files. Here are two approaches to address this:

 * Use Mesh Adaptivity:

 * ANSYS Mechanical offers mesh adaptivity features that refine the mesh based on specific criteria while preserving element IDs. This ensures your journal file remains compatible with the refined mesh.

 * Programmatic Renumbering (UDF):

 * If mesh adaptivity isn't feasible, consider creating a User Defined Function (UDF) to remap IDs in the journal file based on the new numbering scheme. This requires some programming knowledge but automates the process.
