OVERSET grid
 

Has Fluent got the possibility of using overset meshes? Can't find anything on the user's guide. Gino

There's no OVERSET in Fluent. We've run into the problem where we have some contracted CFD work that was done with an OVERSET grid, and now we can't use it on Fluent.

Sorry, and goodluck Jason

Hi,

The alternative of overset grids is dynamic mesh in Fluent. I dont think overset grids will be employed into Fluent. Up to me, dynamic mesh is better cause as far as I know overset grids do not work with unstructured mesh at the moment and the interpolaton between two grids results in loss of accuracy. On the other hand, the drawback of dynamic mesh is the time consuming remeshing and not having the guaranteed mesh quality.

Hi,

Overset mesh is a new feature in Fluent R17.0

[Overset Mesh] in Fluent R17

Currently compatible for:

Steady and transient (fixed mesh), 3D and 2D planar
Pressure-based coupled solver
Incompressible density method
Single-phase or volume-of-fluid (VOF) multiphase
Heat transfer
k-epsilon and SST k-ω turbulence models

BETA in ANSYS Fluent 17.0:

Moving mesh
Compressible flow
VOF with surface tension
Pressure-far-field boundary condition
Workbench support
Pressure-based segregated algorithms

Best,
