Robot problem modelling an elliptic shell structure

Anonymous
Not applicable

Hi, I am new modelling on Robot.

I have been trying to model an Elliptic shell structure of concrete, 6 cm thickness in Robot for my thesis project.
The front elliptical arc has a different shape that the back one, also I have an inclination at the bottom part.
I have tried to transfer the model from AutoCAD to Robot but I only get a series of dots and I cannot get the surface.
Do you guys have any idea how to do it?
Thanks
Jorge Vazquez

Hi @Anonymous 

 

I have recorded this type of structure creation procedure (see attached link). 

 

Elliptic shell structure

 

Main steps presented in recording (predefined grids were used to control geometry)

  • bottom contour lines definition
  • arcs definition (arc discretization and bar creation options on)
  • arc grouping
  • grouped arcs deformation (to form elliptic shape)
  • groups exploding
  • panel definition (using list of object method)
  • panel mesh parameters definition (Coons method, user division definition)
  • panel thickness definition
  • unnecessary bars deleting
  • supports definition
  • calculation
