Unfold a 3D cylinder (with grid points)

Posted by Vinodh at October 02. 2012
Is it possible to unfold a 3D tubular/cylindrical geometry into a 2D using Salome. Can you please help me with this.

Could you precise what you have as input and what you want to get as a result?

Hi Micheal,

I have a 3D cylinder that I need to cut longitudinally stretch it as a parallelepiped and reduce  the 3D domain to a 2D plane. I have 8 layers in my cylinder. my 2D object should be like a stack of these 8 layers...

SALOME can't provide a 2D geometrical object as an unfolded 3D one.

The only possibility I see is to mesh your cylinder and move it's facets into a plane.

Thanks Michael for your reply. I have the 3D mesh of my cylinder. Can you tell me how to split the facets into a 2D plane?

There is no a dedicated function in SALOME but it's possible to do thit in a Python script. It's a very interesting task but it requires some time to implement. Can you wait?
