Default Boundary Definition

Hi,

I am a new user. I have a voxelized random packed of spheres. I have created mesh for simulation with CFD. I can import the mesh; however, there is no inlet or outlet boundaries. I do not know how can I define the boundaries. I would appreciate if you could help me. Thanks...

Are you exporting the surface via VRML-Export?

Hi,

I am sorry, I cannot understand the problem. What I have done is that segmentation, surface construction and mesh generation. I exported the mesh data as Fluent format (.cas). When I open the mesh in Fluent Ansys, I saw only two surfaces; interior and exterior. For simulations, I need to define inlet and outlet boundaries. I do not how to define. Thanks.

Try to attach a "VRML-Export" module (in Compute) to surface, to export it to wrl file.

I think Fluent Ansys can open this files, that doesn't have this problems with boundaries.

Boundary mesh, which is 2D surface mesh, needs to be created to represent boundaries used in CAE software. We are working on a white paper to describe in detail the necessary steps. Stay tuned.
