DLC Dislocation Program List
Basic Programs
Making Models:
- makemodel
- Makes a model parameter (.PAR) file and a model dislocation (.DLC)
file by querying user for geometric details of each dislocation.
- genmodel
- Generates a model .DLC file containing an array of vertical
rectangular dislocations.
- segs2dlc
- Converts line segments (from digitized faults, for example) into a
model .DLC file of stacked vertical dislocations.
Calculating Elastic Fields:
- elfpoint
- Calculates various elastic fields (elf's) at an observation point
in the halfspace or at a list of points.
- elfgrid
- Calculates various elastic fields (elf's) over a grid of
observation points. The grid may be horizontal or dipping.
- elfpatch
- Calculates tractions and deltaCFF's on all dislocation surfaces
(patches) in the model, both active surfaces and fixed surfaces.
Processing Elastic Field Results:
- stroop
- (Stress on optimal planes.) Calculates Couloumb failure function
(CFF) on optimal planes over an observation grid. Also phi-value and
principal component values can be output. Input is the six stress
component grids output by elfgrid.
- strop
- (Stress on planes.) Calculates Couloumb failure function (CFF) and
stress components on planes of specified orientation. Input is the six
stress component grids output by elfgrid.
Making Line-Files for Plotting:
- modellines
- Generates a line file for plotting that contains the outlines of
the dislocation model projected onto an observation grid output by
elfgrid. Uses .PAR and .DLC files as input.
- displines
- Generates a line file for plotting that contains either
displacement arrows or a displacement mesh. File is made from the 3
displacement component grids output from elfgrid.
- bblines
- Generates a line file for plotting that contains focal mechanism
style beachballs to indicate the orientation of the stress tensor. File
is made from the six stress component grids output from elfgrid.
Displaying Results:
- gclrx
- (Xgridcolor) Plots grids in color (or in gray shades) in an
X-window. Allows lines to be plotted also. Output metafile can be
converted to Postscript or Adobe Illustrator format.
- xss
- (Xseeslip) Plots dislocations in oblique views. (Messy program
that needs cleaning up.)
Solving Boundary Value Problems:
- infl2
- Generates a file of influence coefficients to be used by bvds
for solving boundary value problems. (This version does not allow
opening mode.)
- bvds
- (Boundary Value Dislocation Solver.) Solves mixed boundary value
problems. Allows time stepping with driving forces, slipping segments,
and failing segments. Influence coefficients must first be calculated
using infl2
Other Programs:
- dlcmom
- Calculates total moment of slip in a .dlc dislocation model.
- dlcprj
- Projects or unprojects dislocations.
- ptprj
- Projects or unprojects individual points.
- grid programs
- Manipulate standard grids.
- line programs
- Manipulate line data files.
- reg2trac
- Displays a regional field in global 1,2,3 coordinates and
calculates resulting tractions on planes of any orientation.
