To illustrate the capabilities of TwinMesh, let's consider a sample application: the simulation of a 2D lobe pump. Lobe pumps are commonly used in industries such as oil and gas, food processing, and pharmaceuticals.
The TwinMesh workflow (Figure 3) is as follows: (1) import the rotor geometry, (2) define the rotors 1 and 2 (difference in colors), (3) define the circular cases for both rotors, (4) create the interface on the current rotor position, (5) generate grid, and (6) grid quality check. Depending on the appearance of the interface and the quality of the mesh at the current rotor position, the interface and grid should be generated for the other rotor positions that the simulation is considered.
