Stresses @ the int.Point visualization

disladisla
Hello,

I have a .dat file for a unique element with coordinates and stresses according to the standard ccx format.
¿Is there any chance/trick to import those int.Points as new nodes with their stress values assigned to them?.
¿Maybe with an script?. That would be awsome.

    Sorry, Another question related to this.
    My main problem is that I'm interested in certain values at the integration points but only those close to a specific face.
    From the dat file it is puzzling to extract which are the int.points of interest.
    I'm able to import the int.Points as nodes using their coordinates from the .dat and creating a new inp but I'm not sure how they are renumbered during the import process.
    ¿Can I be sure that the new imported nodes are created in ascending order according to the .inp file?. What if I have two elements?


  • VictorVictor
    The renumbering of non-sequential nodes is a bit complicated, sorry. When Mecway reads a .inp file, it creates dummy nodes to fill the numbering gaps, then deletes them in reverse numerical order. Deleting a node means replacing it with the node of highest number. So yea I'm not sure if you can or should try to untangle that algorithm.

    Maybe you could add your own dummy nodes to fill the gaps so the numbering of the real nodes is retained?

    Thanks Victor,

    I will try that. There is a shell expansion in between so i will have to see how to manage that as new nodes are also created. I also found that unused nodes don’t show in the solution.

    HI Victor,

    I'm comparing the SXZ value at the integration point with the SXZ value from the interpolation tool and they are different. ¿Should I assume the interpolation tool is made from the nodal values?.
    In case it is, ¿Would this be hard to do from the integration Points?

  • VictorVictor
    If this is CCX, then Mecway only uses nodal values. It doesn't currently import integration point values from the CCX solution. Including integration point values wouldn't be trivial since it doesn't currently have any way to store or display them, so there'd need to be a compelling reason.
  • disladisla
    Yep, It is ccx. I have finally plot the integration points at the undeformed geometry as reference and interpolated the values known their coordiantes.
    Thanks
