🚀[FEA]: Spatio-temporal Fourier feature in modulus models ?

[SandrineRakotonarivo]

Is this a new feature, an improvement, or a change to existing functionality?

New Feature

How would you describe the priority of this feature request

Critical (currently preventing usage)

Please provide a clear description of problem you would like to solve.

I am willing to use spatio temporal Fourier feature network for modeling wave problem. The online documentation discusses it but the spatio temporal Fourier feature network is not in the repository fodler (models). However, in the example section of the Github repository, data for testing spatio temporal Fourier feature network are there but not the test code. Has the spatio temporal Fourier feature network already been implemented but is missing? Or this model is not part of Modulus? If not, that would be a great new feature. Thanks in advance for your feedback.

Describe any alternatives you have considered

I have used the multiscale Fourier network but it is different from the spatio temporal Fourier feature that allows to separate time and space encoding and that is more appropriate to wave modeling.

Thanks for the report. The source for that architecture is indeed missing. Will mark this as backlog so that we can address it soon.
