Why is there a runtime error when I try to calculate assignments in larger networks?
Such a runtime error can be a sign of too high memory requirements. You can check this in your Task Manager under “System Performance”. If you cannot reduce the memory requirements through improved modeling (e.g. see FAQ #83), you should use a computer with at least 2 GB, better 4 GB RAM. In addition, you can choose a large enough swap file. (See FAQ #90).
