Gmsh is an automatic 3D finite element grid generator (primarily Delaunay) with a build-in CAD engine and post-processor. Its design goal is to provide a simple meshing tool for academic problems with parametric input and advanced visualization capabilities. Jul 31, 2020.
We present four comparatively simple routes to installing FiPy on Mac OSX. The Fink Installation procedure is appropriate if you are alreadyfamiliar with the Fink package manager.Enthought Python Distribution will get FiPy running in a minumum number ofsteps. The Binary Installation procedure is the next most expedient ifyou have never heard of Fink or if you are not comfortable with it. Pleasesee the more general Installation for detailed installationinstructions. These instructions are not the only ways to set up FiPy onMac OS X but represent the most expedient ways, from our experience, tohave a usable installation up and running.

Attention
You must have an administrator account to install most of the followingpackages.
Gmsh CEnthought Python Distribution¶
This installer provides a very large number of useful scientific packagesfor Python, including Python, NumPy, SciPy, Matplotlib, and IPython.
Attention Writing programs for mac os x.
PySparse and FiPy are not presently included in EPD, so you will needto separately install them manually.
Binary Installation¶
Attention
Choose this method if you have never heard of Fink or if you are notcomfortable with it for any reason. Binary installation is the fastestway to get FiPy https://alexbrown817.weebly.com/macdrive-10-pro-crack.html. up and running, but may offer less flexibility in thelong run.
Pre-built binaries for many of the required packages are available athttp://pythonmac.org/packages/py24-fat/.
Python¶
Python is pre-installed on Mac OS X, but installation of other packagesis much easier if you upgrade to the latest version ofpython-2.4.X-XXXX-XX-XX.dmg` from pythonmac (or possibly some variant onUniversal-MacPython-2.4.X-XXXX-XX-XX.dmg`). Your existinginstallation will not be harmed.
Note
Gmsh Api
Any command-line instructions that start with python will eitherneed to be explicitly typed as /usr/local/bin/python or you willneed to adjust your $path variable so that this version ofpython is found before the pre-installed version.
Note
Another option is ActivePython, which probably is the most heavilysupported installation on the Mac, but seems to lack readline support,but these instructions
worked for us.
NumPy¶
Download and install the latest version ofnumpy-X.XX-py2.4-macosx10.4.mpkg.zip from pythonmac.
matplotlib¶
In order to see simulation results, you will need a viewer. We recommendyou download and install the latest version ofmatplotlib-X.XX.X-py2.4-macosx10.4.mpkg.zip from pythonmac.
matplotlib requires:
wxPython¶
Download and install the latest version ofwxPythonX.X-osx-unicode-X.X.X.X-universal10.4-py2.4.dmg frompythonmac.
PySparse¶
Download and install the latest version ofpysparse-X.XX.XXX.macosx-10.4-py24.dmg
FiPy¶
Download and unpack the source archive (FiPy-x.y.tar.gz).
From within the FiPy directory, execute the command-line instruction:
Note
You may now choose to install Optional Packages or you may chooseproceed directly to Using FiPy on Mac OS X.
Fink Installation¶
Attention
Choose this method if you are already familiar with Fink or with Linuxpackage managers in general (such as Debian packages or RPMs). Finkinstallation takes considerably longer than Binary Installation, butoffers a wealth of other programs that can make it worthwhile.
The Fink package manager automatically handles the many intricatedependencies involved in building open source software. Fink is based onthe Debian tools and the package manager model will be familiar to Linuxusers.
Xcode Development Tools¶
Some required packages are not available from Fink as binaries, so youwill need to have the developer tools for Mac OS X. They may alreadybe installed in the /Developer/ directory, but a different version maybe required by Fink; see the recommendations at http://fink.sourceforge.net/download
Note
Free registration with the Apple Developer Connection is required.
X11¶
Download google chrome beta for mobile. Open the X11 application.
Set your DISPLAY environment variable to :0.0.
Note
If the X11 application is not already present in the/Applications/Utilities/ directory, it should be available as anoptional package on the OS installation media that came with yourcomputer.
Fink¶
Ensure that Fink is installed and up to date for your OS.
Note
The following steps have been tested with Fink 0.8.1 on Mac OS X10.4 “Tiger”. Variations may be necessary for other OS versions.
unstable tree¶
Follow the directions at http://www.finkproject.org/faq/usage-fink.php#unstable
Note
We recommend that you accept all defaults presented byfinkselfupdate.
Note
“unstable” is not as scary as it sounds. The Fink administrators tendto be very conservative about what packages are designated “stable”.
Remaining Fink packages¶
Execute the following commands from Terminal application (you can usexterm or any other terminal application of your choosing):
Take note of the version of Python that gets installed (python--version). Many other packages, indicated by a “-pyXX” suffix, requireyou substitute the Python version. E.g., Python 2.4 takes “-py24”, Python2.5 takes “-py25”, and so on:
Attention
The matplotlib installation will automatically download and build anumber of other packages. This process can take quite awhile. Werecommend that you accept all defaults offered at the beginning of thisprocess.
Note
If the installation of matplotlib-pyXX fails for some reason, werecommend you execute the install command again.
A few changes are needed to allow matplotlib to run:
Gmsh Download Mac Os X High Sierra
You may now choose to either edit the “backend” configuration in~/.matplotlib/matplotlibrc to read:
or you can install wxPython with:
(the second choice takes awhile, as it needs to build things).
PySparse installation¶
Download and unpack the latest version ofpysparse-X.XX.XXX.tar.gz
From within the PySparse directory, execute:
![]() FiPy installation¶
Install FiPy packages as explained above.
Note
You may now choose to install Optional Packages or you may chooseproceed directly to Using FiPy on Mac OS X.
Optional Packages¶IPython¶
This interactive Python shell is nicer to use than the default, andintegrates nicely with matplotlib. Download the source and follow thebuilding and installation instructions for Mac OS X.
Gmsh¶
If you wish to run examples that have unstructured meshes, it isnecessary to install Gmsh. Download and unpack the latest version ofGmsh for Mac OS X. Create a link on your $path or a shell alias thatpoints to <Gmshpath>/Gmsh.app/Contents/MacOS/Gmsh.
Note
This is a required package for superfill examples.
Mayavi¶
Mayavi 2 is a requirement if you wish to view 3D problems or improve theviewing capabilities of the superfill examples. The standard instructionsfor either installing with Enthought Python Distribution or installingmanually work fine.
If you have already followed the Fink Installation instructions, thenyou should be able to go to the command line and type:
SciPy¶
This is a very powerful set of tools that augments the capabilities ofFiPy. Although not required for using FiPy, some tests will fail if itis not present:
You are now ready to proceed to Using FiPy on Mac OS X.
Using FiPy on Mac OS X¶
We do a substantial amount of our FiPy development on Mac OS X, so youcan assume that it is well-tested on this platform. See Using FiPyfor more information.
IDLE Environment¶
For those that are averse to the command line, the IDLE environment isinstalled by the pythonmacPython installer and will appear in theMacPython 2.4 folder of the Applications folder. Download ad blocker safari mac.
Attention
We have no experience with using the IDLE environment on Mac OS X,but the following steps do work.
You can use the IDLE file browser to open the examples and run themodule.
The script will open in an editor window.
A matplotlib viewer should appear and the Python Shell should prompt youthrough a series of examples.
Gmsh is an automatic 3D finite element gridgenerator with built-in CAD and post-processingfacilities. Its design goal is to provide a simplemeshing tool with parametric input and advanced visualization capabilities. It is built around four modules: geometry, mesh, solver, and post-processing. The specification of any input to these modules is done eitherinteractively using the graphical user interface(based on FLTK and OpenGL) or in ASCII text filesusing Gmsh's own scripting language.
