Convert a hex mesh to quad?

Posted by s1291 at May 03. 2020

Is it possible to convert a hex cell (3D) to a quad (2D) by projection along a given vector in Salome MEsh module?

Thanks

Hi

I can't imagine what you mean. Can you give an example?

@Saint Michel

Sorry I don't understand what do you mean by 'input data'. I have a 3D mesh. just to make things clear, suppose that my mesh consists only of 1 Hex cell, how to convert it to a quad cell.

 

Thanks

If you want to use the projection, then you need some object, say a plane, to which you project, and a vector. If you project a hexahedron to a plane, by piercing the plane by straight lines originating from 8 vertices of the hexa, you'll get 6 quadrilaterals.

Isuppose that my mesh consists only of 1 Hex cell, how to convert it to a quad cell.

Maybe Generate boundary elements is something like what you need. But it in no way ralates to the projecting.

Thank you for your reply

I've used Modification > Remove > Nodes, to get rid of the undesired nodes.
