What is the shortest way to get the Stress v/s Strain output at a node in tabular format from HyperView?

 

The current way which I know is to plot the stress first in HyperView in Graph using Create Curve and Live Link Option, then to animate it using "Set Transient Animation Mode". Then export the curve (which is increment in Step vs Stress) as a .csv format.

 

Similarly do the following for Strain.

 

Then club those two .csv files to get the Stress v/s Strain data in tabular format.

    that's the easiest way, if you're requesting elemental stresses/strains.

    Because HV needs to perform the average to bring them to nodal values.

     

    The workaround would be to request direct nodal stress/strain, such as GPSTRESS and GPSTRAIN in OptiStruct.

    Once you have them, you can directly launch HyperGraph and use it to plot the Stress x Strain curves for a particular node and export them.

    Or you could also use Altair Compose to load these and write a CSV file easily from there.

    Addiitonaly, you can request GPSTRESS/GPSTRAIN in an ASCII(text) format, using the OPTI output format.
