Currently the tip.Isactive and CrackBody.Isactive primarily depend on their geometry member.Rtips, which only check the tip against the domain boundaries. This is okay for single crack. However, when there are multiple cracks, this approach should be updated:
- Keep the Rtips as those which do not cross the boundaries.
- Use the ACTIVETIPS for the Rtips that are annihilated by other crackbodys.
