from ORPHAN MESH to Geometrical. Model

[alexzive]

Hello Everyone,

Maybe this is a stupid question, but do you think is it possible to get a geometrical model from an Orphan Mesh making some reverse engineering?

Consider I am working on 2D models/mesh.

I know that OM are those meshes without a geom. model, but I would like to know if there are some tricks with other pre/post-processors that can manage it (actually in a 2D mesh should be enough information to re-build the geom. model, isn't it?)

My final goal is to export an orphan mesh as IGES file.

Many Thanks, Alex

alexzive,
I know this can be done with Hyperworks software. I do not think this can be done with ABAQUS CAE.

Hi Alex.

I don't think there's such a thing as a stupid qustion

You can export a 2D geom from Abaqus by printing out the node co-ordinates and then reconstruct the geom into 3D using a compatible CAD software, but you would have to run some python scripts. What my group usually does is create a set of the geom we wish to export. We run the macros necessary to extract these nodes. Or you can choose to export all the nodes and then choose the necessary ones to create your splines etc.

Try the link below to a research paper that uses this method (page 243). The Appendix seems very complete.

Hope this helps,
