Extracting geometry from orphan mesh

Extracting geometry from orphan mesh

(OP)

Hi
Dear Friends

 I am trying to use * map solution option in abaqus. I use CAE. I have imported the deformed shape from odb but it is in orphan mesh form.Is it possible to extract a solid geometric part from it in cae?

Thanks

You can export it as a VRML or an 3DXML. VRML is more useful as it can be imported into other CAD packages (although most do a bad job and generally fail). From there, you can export it as igs or other formats you're interested in. The VRML will be composed of lines when imported into another package. I use Rhino with some success. Best of luck.

Hi
Thanks , I will try that although it apparently includes some deficiencies.there most be a command in abaqus to perform this directly.

Regards

From your orphan mesh you can build a geometry with the following commands:

orphanPart=mdb.models["Modelname"].parts["Partname"]
mdb.models["Modelname"].Part2DGeomFrom2DMesh(name="newpart_name",part=orphanPart,featureAngle=0)

HI
Thank you 76185 ,
As you have said i found the related code lines in examples.
What should i do now for solution mapping? I consider next steps as follows :
remesh the deformed shape and introduce boundary conditions and loads once again
write input file and add * map solution and step and increment numbers to it
Now , how should i make abaqus understand from which job and database should it read the nodal values and map it to new job?

Thank you very much for you help and
Best regards

I am not sure to answer to your question but you can use the PredefinedField function to assign the last stresses to your new nodes.
