Hi everyone,
I have been trying to create a DeepONet model in Modulus for a fluid flow through a pipe. Unfortunately IntegralBoundaryConstraint does not seem to work for DeepONets and I cannot figure out how to implement a constraint similar to it. Moreover, the model simply converges to the zero-flow without any integral continuity constraints. I tried to use IntegralLossNorm as the loss in DeepONetConstraint.from_numpy, but I am not sure if that is the right idea. Has anyone tried something similar?
Best,
Andreas.
