How far reaching is TVK?

[Michael Krasowski]

Hello all! 

I work in FloPy predominantly and I recently noticed the TVK utility/package allows you to input the package you're making time-varying into the utility ( flopy.mf6.modflow.mfutltvk.ModflowUtltvk() ) with the input "parent_package". Is this input intended to exclusively be NPF package FloPy objects? Or can this utility work with other non-time varying packages? I am interested in making VKS and some of the other UZF packagedata inputs time varying if at all possible.

If this isn't the case, do you think it's worth making an issue on GitHub to get the UZF package included in the time varying infrastructure? Seems like being able to change the aquifer conductivities/porosities, but not the UZF conductivity/porosities could lead to some modeling concepts/structures that are at odds with each other.

Thanks,
Mike
