Determine node labels , when the co-ordinates are known( Abaqus)

[chethangouder]

Dear friends ,

I have to extract strains at certain points in a Abaqus model. Is there a way where i can extract strain values using the nodal coordinates to refer to the nodes .

Or ... Is there a way to know the node label, if we know the nodal coordinates

Thanks and Regards

You can determine the node label from within CAE by using the "query option" and then simply selecting the nodes that you are interested in. As an alternative you can search the inp-file for the coordinates and that way determine the node label.

Dear Sir,

I am doing a convergence study . Where i have to keep changing the mesh size . The location of some nodes in the model have been fixed by partitioning the model.I have to measure the strains at these nodes when the mesh size is changing. The only information with which i can refer to these nodes are the nodal coordinates.

My Concern is : The nodal information in the input file begins at "* Node" line and ends before "*Element" line. I have to read the data between these lines . Can you please tell me how i can use python to read this data ...

Thanks and best regards

Python would be an excellent tool for solving that problem. Unfortunately I don't have the time to write the Python code, but that are tons of great Python tutorials available on the web.
