How to create thin (0 thickness) internal walls in ANSYS CFX and Fluent

Three videos showing the CAD topology required to create thin internal walls for CFD simulations, and how to set up the boundary condition in ANSYS CFX & ANSYS Fluent.

Often internal walls such as baffle plates or turning vanes are very thin. By creating a wall with 0 thickness (thin wall) we avoid having to apply mesh across the wall thickness, which would result in either a high node/element count or a highly skewed mesh.

The process for creating a thin internal wall boundary condition is to:

  • Create a common surface between 3-D volumes in the CAD model where the wall is located.
  • Set the Share Topology to Merge in ANSYS SpaceClaim to ensure a 1 to 1 conformal mesh.
  • Create a Named Selection on the internal wall surface in ANSYS Meshing.
  • Import the mesh and create a wall boundary condition on the Named Selection in either ANSYS Fluent or ANSYS CFX.

Thin wall topology

This video shows 3 different models (baffle plate, pipe injection and turning vane) and the topology used when modeling both with a wall thickness and as a thin wall.

 

 


Thin Walls in ANSYS Fluent

This video shows how to create the internal wall boundary condition once the mesh is imported into Fluent, and the effect of Named Selections on this process.

 

 


Thin Walls in ANSYS CFX

This video shows 2 methods of creating the internal wall boundary once the mesh is imported into CFX.
