Motivation

We would like to evaluate the use of NEML2 to evaluate the a reduced order model based constitutive model for a solid mechanics simulation. The reduced order model is a LAROMANCE model from LANL that is computationally expensive. NEML2 should speed up its evaluation by using vectorization to compute multiple material points simultaneously on both a cpu and gpu.

Design

I will follow examples of NEML2 models already available and implement the multilinear interpolation version of the LAROMANCE model provided by LANL.

Impact

NEML2 will provide a speed up in simulation time.

adding laromance model to neml2. This works for interpolated material…

… where I am just calling neml2 to perform an interpolation but I am not integrating the material in time.

Small change to NEML2 action for case where I just want to interrogate the neml2 model and not integrate it in time.

laromance grade 91 from type model implemented in NEML2.
e910ca3 
This is based on a grade 91 model from LANL on 2/1/2025.
The implementation uses a dummy inteprolation grid, values, and transforms and does not contain any real material data.
The actual grade 91 data is in Bison.
This implements multilinear interpolation.
There are 6 interpolation axes and 3 values at each node.
The interpolation axes and interpolated values are transformed.
This contains examples where the model only performs interpolation and a full example with radial return done in NEML2.
The radial return mapping requries a change to NEML2 in math.cxx that Gary is including in his neml2 udpate
