Axial pump using Moving Reference Frame in OpenFOAM

To simulate the rotating mesh problems you need to understand the Arbitrary Mesh Interface (AMI) concept:

• AMI enable simulation across disconnected, adjacent, mesh domains for rotating geometries
• AMI require separate meshes for rotating and/or static regions of geometry, which are coupled at patch boundaries through the cyclicAMI boundary condition
• AMI patch boundaries requirement that the patches conform fairly closely to one another.
