[tag] overwrite_mesh_data

Overwrite mesh data based on material ids.

The <overwrite_mesh_data> tag contains <remove>, <set>, and/or <take_original> elements that define how to modify mesh data fields for specific material IDs or mesh items.

Available operations:**

  • <remove> - Remove a mesh data field entirely
  • <set> - Set a mesh data field from a parameter value

  • <take_original> - Restore the original mesh data (useful after previous overwrites)

    Example:**

<overwrite_mesh_data>
<remove>
<field_name>old_data</field_name>
<mesh_item_type>cell</mesh_item_type>
</remove>
<set>
<field_name>temperature</field_name>
<mesh_item_type>node</mesh_item_type>
<material_ids>1</material_ids>
<parameter_name>temp_param</parameter_name>
</set>
<take_original>
<field_name>temperature</field_name>
<mesh_item_type>node</mesh_item_type>
<material_ids>0</material_ids>
</take_original>
</overwrite_mesh_data>
