This is not set up correctly because I am getting the error:
The NEML2 model requires a stateful input variable `old_state/cell_dd`, but its state counterpart on the output axis has not been retrieved by any object. Therefore, there is no way to properly propagate the corresponding stateful data in time. The common solution to this problem is to add a NEML2ToMOOSE retriever such as those called `NEML2To*MOOSEMaterialProperty`.

I think you need to save the corresponding neml2 output variable into moose. The output variable should be state/cell_dd.

Thanks Gary, This fixed the input file problem. I updated the input file. I'm going to work on the problem with the batch sizes now.

Gary gave me a fix for the batch size problem I had. The fix goes in NEML2. It is from linear algebra library changing between libtorch versions. I am using pytorch version 2.1.2.post4 and I need this fix. Gary is using 2.5.1 and does not need the fix.

@dschwen @hugary1995 This is the LAROMANCE implementation in NEML2. I am still converting the radial return mapping input file over to the new syntax. I left a comment about the error I'm getting. |

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 closes idaholab#29774
