ABAQUS/CAE 3D Model

ABAQUS/CAE 3D Model

ABAQUS/CAE 3D Model

(OP)
Dear all,

Could anyone shed some light on constructing a 3D model in ABAQUS, which cannot be build by simple extrusion, revolution or sweep. I understand that I can build models in CAD and use it as an input for ABAQUS. The only other software I have is MATLAB. Any ideas on how I can build such models directly in ABAQUS/CAE ?

Thanks,

Rakesh  

RE: ABAQUS/CAE 3D Model

What kind of structure? Wireframe, solid or shell?

RE: ABAQUS/CAE 3D Model

Well, with the right amount of patience and skill, you could write a code to parametrically generate a solid element decahedra (generating a nodal coordinate matrix and element matrix), but for complicated shapes it's most efficient to generate an .igs in a CAD package. I know Abaqus doesn't house the most user friendly CAD GUI, and that is why it's sometimes better to use a program like SolidWorks, Autocad, etc. Academic versions are cheap, otherwise you have to spend a lot of money or get creative...

RE: ABAQUS/CAE 3D Model

If you are modelling stand-alone dodecahedral geometries you can generate them by drawing individual faces as shell parts. Assemble them appropriately, merge them and convert the resulting shell to a solid. You could script this with python or if there are a reasonable number of repeating faces on your geometry you can do it manually.

Thanks for all the suggestions. I was able to create a simple decahedral model by using the extrusion feature first and then by creating sections and deleting unwanted features. Thanks for the help and suggestions.
