===================================================================================== surface deformation generated by a dislocation burried at depth in an elastic space ===================================================================================== program rngchn computes surface deformation generated by a dislocation burried at depth following Okada's formulation of elastic deformation. more detailed explanations can be found in rngchn.ps to run the program, just type : rngchn : file containing surface grid specification, that is where exactely on the surface the program should compute deformation. on a regular 2-D grid, along a 1-D profile? how many points ? etc etc : file describing precisely : - the geometry of the plane on which the dislocation takes place. depth, dip, strike, length, width - the 3 components of the dislocation u1, u2, u3 to be applied : file containing the output deformation : what type of output one wants exactely. vectors, components, residuals with respect to data, projected and wrapped values for simulation of interferogram, ascii, binary etc etc the principal usefull are the following : vectors : the 3 components of surface displacement are output ascii : only one component is output, in ascii residual : only residual values (data - model) are output the grdspec file contain usually only one line :
