3D cyl mesh

• originally from pr: #36
• commits from: @lheagy
• review from: @rowanc1

3D Cyl Mesh

First implementation of a 3D cylindrical mesh. We discretize in r, theta and z.

Operators

• edgeCurl
• faceDiv
• aveF2CC
• aveF2CCV
• aveE2CC
• aveE2CCV

are all implemented and tested for second order convergence

Examples

There are some examples running this code in http://github.com/lheagy/casingResearch

• added a simple example that plots a 3D cyl mesh

Plotting

• add plot capabilities for plotSlice (and I think two slices through the mesh for plotGrid())

Testing

• basic elements like the grids, counting of things.
• operator tests for mimetic properties

Other updates

Cell Grad Stencils are properties

• cell grad stencils are properties rather than methods. This pr will need to be followed by an update in the SimPEG regularization (addressed in simpeg/simpeg#699)

minor updates

• plotting now uses the C0, C1, ... colors in matplotlib
• added *.ipynb to .gitignore

plotSlice upgrades

• from pr #92
• commits from @micmitch
• review from @lheagy

upgrades in plotSlice

• Added range_x, range_y, and sample_grid input arguments to plotSlice function.

stream thresholds

• from pr #91
• make the stream_threshold compatible with plotslice

VTK updates

Just a few small changes for vtk mesh IO in python 3

• from pr #89
• commits from @jcapriot
• review from @lheagy

Tree mesh cell grad

Cell grad operators for TreeMesh inversion

• from pr #72

• commits from: @fourndo, @micmitch, @sgkang, @lheagy

• review from: @rowanc1, @lheagy, @jiajiasun

• First pass implementation for stencil operators
  Initial implementation without hanging faces
  

• Second implementation with hanging faces
  

Smoother gradients on Octree change.

• Create gradient operators with dimensions for PDE problems.
• Add unit tests for operators. Thanks @micmitch and @sgkang

Solve DC problem in mine tunnels.
Tree mesh examples will follow shortly on SimPEG ... stay tuned.

aveCCV2F

• commits from @sgkang
• review from @rowanc1, @lheagy
• originally from pr #88 and discussed in issue #87

create aveCCV2F, which averages a cell centered vector to faces and is useful for self-potential problems

Option to mask streamlines

From pr: #86
Commits from: @lheagy
Review from: @thast, @rowanc1

add the ability to mask streamlines if the amplitude is below a given threshold (stream_threshold).

add IO functionalities to write DCIP2D mesh and models

From pr #84

• commits from @thast
• review from @lheagy

add IO functionalities to write DCIP2D mesh and models

• the MeshIO functions writeUBC and writeModelUBC are now compatible with 2D meshes and models.

• We now make sure that mesh and model get saved at the same place by giving the option to specify the folder outside of the filename (before the folder was given by the dict.keys, not very practical)

• The upgrade is backward compatible

h_gridded

New mesh property: h_gridded

• From pr #77
• commits from: @dccowan, @lheagy
• review from: @lheagy, @rowanc1

This function works for TensorMesh and TreeMesh types. Much like gridCC, h_gridded returns [hx,hy,hz] as a nCxdim numpy array. This function is important for multiple potential fields problems (Mag, VRM, grav) in 3D.
