One of the major new features delivered with R2021x FD05 is the ability to calibrate a material model based on the response of a FE mesh/model.  This is going to be needed for calibration of damage and failure models. Another example where this is needed is for any experiment in which the state of stress/strain is non-homogeneous, such as in indentation testing, 

FE-based Material Model Calibration

Another major new feature delivered with R2021x FD05 is the capability to calibrate the PRF model (only in numerical mode) using DMA test data - storage & loss modulus data, which is useful for tire simulations and other elastomer products such as bushings and mounts.  At this time we do not have any shareable DMA test data taken at multiple mean strains, or multiple dynamic strains (needed to calibrate nonlinear viscoelasticity).

An earlier version of the Material Calibration app allowed for calibration of the Hyper+Prony model in analytical mode using DMA test data.

The Material Calibration app has, for some time now, supported the calibration of elastomers using time-domain test data  (for both linear viscoelastic, Prony series, and the nonlinear viscoelastic PRF model).  Please reference the post Sharing Material Test Data, where you will find test data Butyl Rubber, a family of strain-rate curves and a video on how to calibrate that data shown in my post Calibration App in the 3DExperience Platform - 2019x FP1923.
