Function to Generate elev.th File

[mansurjisan]

We are currently working on setting up the Duck, NC test case for the UFS Coastal App using PySCHISM. While working with this test case, we identified a need for a function in PySCHISM to generate the elev.th file. This file, which contains time-varying surface water elevation data in ASCII format, is provided with the test case, but we are unable to recreate it using the current PySCHISM functionality.

Is there an existing method in PySCHISM to generate this specific elev.th file, matching the format and content of the one provided in the Duck Island test case? If not, could you provide guidance on how we might implement this functionality or suggest an approach to create this file programmatically?

This would greatly help automate test case setup and understand the input file's generation process.
