Hi @MarekRuzicka
The error:
raise RuntimeError(“Failed Unrolling Graph”)
RuntimeError: Failed Unrolling Graph
Means you’re requesting some variable to be computed that cant. What are the names of the variables in output_vectors. Based on the script you provided it should be {'Entw1SiiIVentilKV1t3': np.array(N,1)}. Similarly input_vectors should be something like {'t0': np.array(N,1)}.
Theres some other posts about this error that could help:

Hi,
i am using modulus for a problem similar to the “conjugate heat transfer” example.
First i started by setting the equations with time=False like in the example. Everything worked fine. For my problem i need to insert the time variable so i decided to switch to time=True. This resulted in the following error:
