Interseismic model

[ranneylxr]

Inversion model:

1. TDEFNODE from McCaffrey.
   using rectangle dislocations; needs pole information of blocks;
   fortran code can not be modified. => Difficulty for extracting the forward modelling part (!)
2. BLOCKS from Meade, B.J. and J.P. Loveless
   using triangular dislocations => user must define the triangular patches as input (now: no software found!)
   matlab code
3. PCAIM from Andrew Kositsky
   seems no part about forward modelling.

Others:
1.TDE from Meade, B.J.
using triangular dislocation to calculate deformation in a uniform elastic half space. But users must define the triangular dislocation by themselves;

Triangular generator:

1. mesh2d from Darren Engwirda
   the output is delaunay mesh grid.
2. FaultSampler from Barnhart
   do triangular patches dividing during the distributed slip inversion, which is a problem. But he used mesh2d to get the initial delaunay mesh grid.

Now the question is:

1. Extracting forward simulation part from those Inversion models
2. Knowing how to use triangular dislocation to describe the fault surface.
