Incorporate pygridgen/pygridtools? #121

Closed phobson closed 8 years ago

phobson commented 8 years ago

I noticed that FloPy and can interface with the gridgen-c executable.

I don't quite yet grok the complete workflow of that interface, but I wonder if there would be some benefit to interfacing to pygridgen/pygridtools?

pygridgen was originally authored by Dr. Hetland at Texas A&M. I maintain a modern fork of the project here: https://github.com/phobson/pygridgen http://phobson.github.io/pygridgen/tutorial/gridgen_examples.html

And then to minimize the divergence of my fork from Dr. Hetland's (there's still hope he'll pull in my changes), I created pygridtools for a higher-level interface: https://github.com/Geosyntec/pygridtools http://geosyntec.github.io/pygridtools/tutorial/02_ShapefilesAndCellMasks.html#loading-data-from-shapefiles-via-pygridtools-iotools

Again, I'm still parsing the code that interfaces with gridgen-c, so this might all be moot if all flowpy needs is a pair of numpy arrays.

Paul, it looks like there are two different programs called gridgen. The gridgen that is currently supported (somewhat) in Flopy is the version distributed by the USGS (http://water.usgs.gov/ogw/gridgen/). I had not seen the gridgen-c program that you mentioned.

Ahh. I see.

I'll keep digging and see if there's a way to take pygridgen grids and making them useful for flopy. In meantime I'll close this issue.

Apologies for the noise.
