Discover the innovative technology of TwinMesh and how it revolutionizes the field of meshing.

Introduction to TwinMesh

TwinMesh is a revolutionary meshing technology that has transformed the field of mesh generation. It is specifically designed for the simulation of positive displacement machines, such as pumps, compressors, and motors.

With TwinMesh, engineers can accurately model the complex geometry and flow behavior of these machines, allowing for more accurate simulations and analysis. This technology enables engineers to optimize the performance, efficiency, and reliability of positive displacement machines, leading to significant advancements in various industries.

The simulation workflow starts with generating the grid for the machine with TwinMesh. The stator component could be meshed with Ansys meshing and combined. The preprocessing and simulation can be performed with Ansys tools such as CFX-Pre and Solve. The simulation results can be post-processed with Ansys tools such as CFD-Post or EnSight (Figure 1).

Sample Application: 2D Lobe Pump

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.
