MODFLOW and Flopy on Linux is possible?

[Rodrigo Brust]

Hey, folks! How are you?

Well, recently  I've been shifting from Windows OS to Linux OS, and in this time, I got a new job that requires MODFLOW on my PC.

I'd like to know if there's any way to download it to Ubuntu, besides Wine. 

If not, is MODFLOW via Wine stable? The performance is resonable? 

I took a look in old questions, but there weren't very conclusive. 

I appreciate your help.

Rodrigo.

you can compile the open source MODFLOW fortran codes in linux. There is plenty of documentation on the net. One example can be this:

https://www.simonwenkel.com/2018/04/15/compiling-MODFLOW-on-linux.html

If you are familiar with python, you can also compile MODFLOW using the module flopy-pmake:

https://github.com/modflowpy/pymake

Hatari lab also pre-compiled some stuff here:

https://hatarilabs.com/ih-en/unofficial-modflow-flow-and-transport-executables-for-linux-ubuntu-tested

But I would download the latest version and recompile everything

Good luck

Gio

Statically linked linux executables for the many of the USGS codes (MODFLOW-2005, MODFLOW 6, MODPATH, GSFLOW, etc.) are also available at:

https://github.com/MODFLOW-USGS/executables/releases

For MODFLOW-OWHM I recommend using WINE when it is available on the Linux OS. I do also include an Ubuntu compiled executable binary  along with the download (I call the ubuntu executable bin/mf-owhm.nix ). 

Just an fyi, anything that runs on MODFLOW-2005 and MODFLOW-NWT will run on MODFLOW-OWHM, so if you are working in any of those archs, then it might be easiest to just pull the most recent .nix on there (and let me know if it works).

If you go to

https://code.usgs.gov/modflow/mf-owhm

that will have download links (scroll down past the code) for the latest executable for both windows and ubuntu linux.

It also includes a GNU makefile that can build MODFLOW for linux or windows, but requires either gfortran 10 or intel fortran. Earlier versions of gfortran dont work due to several compiler bugs that GNU fixed in v10 but has yet to backport, so right now Intel is the only compiler option (which is recommended anyways cause it tends to produce faster running executables). 

All you have to do for the makefile is open it in a text editor and answer some of the questions (just following the comments). 

When you are ready to compile you just have to type the word make at while in the directory with the makefile and everything should be handled automatically.

I've tested this makefile on several Linux OSes and Windows running MinGW GNU Make.

*Note that you only need a C compiler if you are using the GMG solver package, which I would not recommend if you do not need to use it (PGCN and NWT are better options).

Hi

You can have executables compiled in Linux under some USGS repositories: 

https://hatarilabs.com/ih-en/a-place-to-find-modflow-executables-for-any-operating-system

We actually have done several models in Linux, mostly working with Flopy. You wont notice the difference between working with Linux and Windows. If you want to work with Model Muse, you can use Wine. 

If you want to fancy around with MODFLOW-OWHM Scott is a nice guy that can give you much support.

Viva el software libre!

Hello, everyone. I really appreciate your help. 

I've already shifted my OS and installed ModelMuse via Wine. Until now, it works good. 

The only challenge I'm facing right now is the instalation of pymake and flopy. I'm struggling with this, and I think I didn't understand quite well.

You guy might help me?

Things I have already done

1 - pip install flopy

2 - pip install https://github.com/modflowpy/pymake/zipball/master

3 - already downloaded the .exe from Github (https://github.com/MODFLOW-USGS/executables) and put in Documents/Modflow/src

The thing is: I'm missing something in the installation that I can't see. 

When I run this pymake example: 

import pymake

pm = pymake.Pymake()

pm.srcdir = 'src'

pm.target = 'mf6'

pm.include_subdirs = True

pm.build()

It returns me this error

I also tried this Hatari Lab's tutorial (https://hatarilabs.com/ih-en/unofficial-modflow-flow-and-transport-executables-for-linux-ubuntu-tested) , but Ubunutu wont let me run the very first line .

I'm kinda lost, I'm quite new to this MODFLOW and Ubunutu world, and there aren't many tutorials. 

My settings

Ubunutu 20.04

Using Python 3.8 in Anaconda Environment

I found the solution in this github issue: https://github.com/modflowpy/flopy/issues/1165#issuecomment-892233629

If you downloaded the executables from https://github.com/MODFLOW-USGS/executables there isn't any need to use pymake to build the executables. You do need to decide if you are going to run the executables in linux or use the windows executables with Wine and download the appropriate zip file for the OS.

To run make_mf6.py in the pymake examples directory you would type:

   python make_mf6.py

This would download the distribution and build the executable using gfortran. If you wanted to build with a compiler other than gfortran you would type:

    python make_mf6.pt -fc ifort

In both cases you would need to have the compiler installed and be able to run it from the terminal.
