Are there any practitioners here who could recommend something along the lines of openfoam for doing moving mesh? I've had no joy in using it but then this probably serves to illustrate my limitations more than anything
Dynamic/moving mesh CFD refers to a computational fluid dynamics (CFD) technique that involves the use of a mesh that changes or moves as the simulation progresses. This allows for more accurate and efficient simulations of fluid flow in complex geometries or with moving boundaries.
The use of dynamic/moving mesh CFD can lead to more accurate results compared to traditional fixed mesh methods. It also allows for better representation of complex geometries and moving boundaries, leading to more realistic simulations. Additionally, dynamic mesh CFD can often reduce computational costs and simulation time.
Dynamic/moving mesh CFD can be beneficial for a wide range of applications, including aerodynamics, fluid-structure interaction, and multiphase flows. It is particularly useful for simulating fluid flow in complex geometries with moving boundaries, such as in aerospace, automotive, and biomedical engineering.
One of the main challenges with dynamic/moving mesh CFD is the development and implementation of efficient and accurate mesh deformation algorithms. These algorithms must be able to handle complex geometries and moving boundaries without introducing errors or distorting the mesh. Additionally, the simulation may require more computational resources and time compared to fixed mesh methods.
There are several techniques used for dynamic/moving mesh CFD, including the Arbitrary Lagrangian-Eulerian (ALE) method, the Chimera method, and the Overset grid method. These methods use different approaches for mesh deformation and are suitable for different types of applications. Some software packages also offer automatic mesh adaptation, where the mesh is dynamically refined or coarsened based on the flow conditions.
