Adaptive Mesh in Multi Phase Flow Simulation Using Ansys Fluent

What is Adaptive Mesh? In this video, on behalf of Alpha Omega team, 3D Dam break, a classical two-phase flow problem, was solved using the adaptive meshing technique in ANSYS Fluent. Mosaic meshing (Poly-hexcore) was used in ANSYS Fluent meshing to generate the mesh with the total number of 50,753 cells. The Volume-of-Fluid (VOF) method was implemented in ANSYS Fluent to simulate the two-phase (air-water) flow in a tank. In order to refine the mesh, only near the gas-liquid interface, the dynamic adaption mesh with maximum refinement level of 2 was applied. It is demonstrated that such dynamic adaptive mesh can successfully refine the mesh near the interface region and keep the coarse meshes elsewhere in the computational domain., which can be helpful to reduce the computational time. Example: 3-D Dam Break Mesh number: 50,753 cells Mesh type: Mosaic meshing (Poly-hexcore) Fluids: air and water Multiphase method: VOF + Dynamic adaption mesh with maximum refinement level of 2 Mesher: ANSYS Fluent Meshing 2020R1 Solver: ANSYS Fluent 2020R1 Get in touch: Phone: (724) 544-0393 Learn more about our ANSYS upcoming Webinars & Events: See what&new with our Blog: #spaceclaim
