Apply Mapped Mesh = Hex Mesh ?

Jerome Teoh

Hi,

 

When you apply mapped mesh to a volume region, I orginally think that is will be a hex mesh.

But looks like it is not from my mesh visualization? It looks like a tet mesh to me.

Am i correct?

 

Jerome.

Hello Jerome,

The diagonal elements you are seeing on isoplot of a cut plane are surface mesh elements. The mesh on the cut plane are surface mesh elements which corresponds to intersection of the cut plane with the volume elements that it cuts out.

Thank you,

Hi Jerome Teoh,

 

You are right, mapped mesh will not create hex surface elements.

If you apply mapped mesh to a volume region the volume mesh elements will be with hex elements(six surfaces volume element), not the surface mesh elements.

 

Best regards,

Alexandru, However, if you look closely to the picture I attached, looks like it is meshing a tet for me. Weird.

Hi Jerome Teoh,

Flux mesh generator splits in two the surface mesh elements on the boundaries of the volumes with mapped mesh when creates the volume mesh elements that link that volume with adjacent one without mapped mesh, to create pyramid volume elements.

You can view the volume mesh elements:

Alxandru,

 

Thanks, any idea how can I do the visualization after solving?

Also, this is what I got when I turn on the isoplot after solving with the cut plan in my middle of the mapped volume.

Looks like there are some diagonal component?

Hello Jerome,

After solving the project, you can activate the mesh elements visualization by going to data tree<Mesh<Volume or Face elements<Right click<Select Add visualization.

Then you can visualize them by going into mesh visualization<Select Volume or Face element visualization.

Thank you,
