Taking the role of the sub-domain and reference numbers into account, it could be useful to change some numbers during processing. For example, when a domain exhibits some symmetries or repetitions, a primal mesh is modified by these transformations. In this case, a number given can be introduced which changes value in order to be able to define different physical conditions. For example:
Sub-domain number 1 Sub-domain number 1 (unchanged)
Sub-domain number 2 Sub-domain number 3 (changed)
Reference number 1 reference number 2 (changed)
Reference number 2 reference number 3 (changed)
The modification modules perform this type of operation.
