Several software components (for example, CFX-Pre, the CFX-Solver, Ansys ICEM CFD, and so on) are used while executing steps in the overall remeshing process. Rather than holding all of these licenses for the entire duration of the analysis, they are only ‘checked out’ as required. Although this frees up the licenses for other users when remeshing is not executing, it also introduces the possibility that required licenses are not available when they are needed for remeshing.

This model for software license handling may cause problems in multi-user environments, but work is underway to provide a broader range of handling options for future releases.
