File conversion from ABAQUS --> Hypermesh -->ANSYS CFX

Hi Everyone,

 

 

I am performing a textile compaction simulation in ABAQUS. I would like to take this compacted textile model to ANSYS CFX to perform flow simulation in an attempt to predict the permeability of this compacted textile. My plan is to voxelize the mesh of this compacted textile model (both the matrix and the fiber tows within the unit cell textile model) before exporting to ANSYS CFX. My predecessor performed this file conversion through:

 

export .vrml file of the compacted textile model from ABAQUS --> convert .vrml file to .stl file in Matlab --> voxelize the mesh by using Aitkinhead's mesh voxelization matlab function --> create .vox file --> convert .vox file to .inp file --> import the .inp file in Hypermesh to perform mesh editing (deletion of floating elements and boundary surface definitions) -->  export .cas file from Hypermesh which can be read by ANSYS CFX 

 

My questions are:

1. I am aware that Hypermesh has the ability to create voxel mesh. Is it more efficient to create this voxel mesh in Hypermesh or before importing in Hypermesh (just like my predecesor did)? If it is better  to create this voxel mesh in Hypermesh, can somebody suggest the steps in going from ABAQUS to Hypermesh?

2. Is there a tutorial that demonstrates voxel mesh creation in Hypermesh?

 

Thank you very much! Really need your kind advice.
