--- Begin Message ---Hi, Actually, the situation is like this. Using a physical entity, we can group different elementary entities into one set. And using many physical entities, we can then create many such sets. And then, we use data mapped to the physical entity. Right? For example, I have elementary entities 100, 101, 102, 200, 205, 300. And I classify them as follows: Physical Entity 1000 = {100, 102, 300} Physical Entity 1001 = {101,102,200} Physical Entity 1002 = {205} Then I can map the data to the physical entity. However what I wanted to do right now was to create such sets in more than one way. Like now I want to have one more classification for different data mapping. This classification is like follows Physical Entity 1010 = {100, 102} Physical Entity 1011 = {101,102} Physical Entity 1012 = {205, 300,200} Now this classification is not possible right now gmsh. So, I was wondering if the tags support extra information of this sort or not. Mainly, there is an entry in Gmsh which says "number of tags". Is the value of that arbitrary or restricted to three? However, what I'm doing now is. I'm reading the elementary entities directly from the file and then have written a C++ program to create data structures to classify them properly. If this could be done in .geo file instead of the c++ program, then the code would be quiet cleaner. Hence, my question. If there was a way to add more than one tag of physical entity to the same element, then I guess it might be easy to use.
