Solving fuselage panel case with two neural network

I am relatively new to physics informed neural network. I am trying to solve fuselage panel problem under NVIDIA modulus, physics informed foundations, linear elasticity example.
The native case is trained using single neural network. I am trying to solve it using two neural network as in bracket case.
I am getting following error. Any help would be appreciated. I have attached my case files and the ss of the error. (6.8 KB)


it seems that you simply have not defined true_outvar in your PointwiseValidator.

If you don’t have ground truth data from simulations, you can use the PointwiseInferencer for visualization.

thank you so much, i was able to resolve the problem.
