Why is a crack assigned a new material ID?

      From the command from the example in the documentation (“tb, cgcr, 2, , , PARIS”). Cracks are usually assigned a different material ID from the underlying material for at least two reasons: a) it’s easier from a user’s standpoint to separate crack parameters as a separate material ID for bookkeeping purposes (e.g., material ID 1 is material, material ID 2 are crack parameters) similar to how we may assign a different material ID for contact (friction), even though contact occurs on the surface of the material b) if a user has more than 1 crack present (e.g., 2 cracks in different locations), we need 2 different material IDs – one for each crack – and using separate material IDs may be easier to track
