Hello.

You have mentioned about RNN and GRU for transient problem in Simnet document.

Would you let me know if you have any plans to develop such a recurrent network architecture for modulus?

Thanks,

Yes, Modulus 22.12 release will have the RNNs

Hi schoudhry,

Thank you for your answer.

Can we use the RNN for 3D transient CFD problem?

Regards,

Hi @yokoi.toshiaki

This is a pretty broad question as this largely depends on the complexity of the 3D fluid flow. However, we have been testing a data-driven RNN model for 3D transient fluid flow with some promising results. 3D fluid systems add a lot of additional challenges in addition to the more complex physics regarding training time, data-loading, etc.

Hi ngeneva

Thank you for your reply.

As you mention the RNNs are promising for data-driven surrogate model.

However we are interested in RNNs for PINNs.
Will the RNNs in Modulus22.12 be available for for PINNs?

For example, unsteady vortex around a cylinder.

Thanks,
