Abaqus Sequential Thermo-Mechanical
Abaqus Sequential Thermo-Mechanical
(OP)
Good morning all,
I'm running uncoupled sequential thermo-mechanical simulations (for AM).
This means that I'm using the .obd file from the heat transfer simulation as a predefined field in the mechanical simulation.
However, I'd like to do a temperature cutoff for the nodal temperatures that are being fed into the mechanical model.
For example, any values over 1500 C would be overwritten to be 1500 C.
Is there a way to do this within Abaqus? I'd rather not have to open and edit the long .odb file by hand.
Thank you for any ideas!

-Generate report from ODB in Viewer GUI in CSV format
-Run MATLAB script to identify temps above threshold value
-Run MATLAB script to replace temps above threshold value with threshold value
-Run MATLAB script to write to new CSV file
-Use UTEMP subroutine to define temperatures at specific time steps and nodes in mechanical analysis
I was not able to use python because of the encryption of the ODB. It would have been difficult to then create a modified ODB with my edited temperatures when the ODB structure was not clear.
Hope this helps someone.
