This post was originally written using a development version of R2021x FD05.

This example uses a mesh of the center region of a dogbone specimen, meshed with 7200 C3D8R elements (large model).  This Abaqus/Standard model takes about 91 seconds to run on 1 cpu, or about 60 seconds to run on 2 cpus (on my laptop).   Some synthetic test data was created using one particular Johnson-Cook plasticity model.  Then this synthetic data was used to see if the calibration app could re-capture this "right answer" through running a series of Abaqus runs.  

Large model: 7200 C3D8R elements, 25653 DOF, runtime ~91 secs, video from May, 2020

Smaller model: 1500 C3D8R elements, 6150 DOF, runtime ~13 secs, video from Nov, 2020

I initially used the larger model because it was something I had on hand.  The larger size makes the calibration times quite long.  Later I revisited this and reduced the model size, still capturing the physics of the necking event.
