- The reader module allows two levels of caching. The OpenFOAM fvMesh can be cached in memory, for faster loading of fields. Additionally, the translated VTK geometries are held in a local cache. The cached VTK geometries should incur no additional overhead since they use the VTK reference counting for their storage management.
