NAME

       GetDP - a General environment for the treatment of Discrete Problems

SYNOPSIS

       getdp [file] [options]

DESCRIPTION

       GetDP  is  a  general  finite element solver using mixed elements to discretize de Rham-type complexes in
       one, two and three dimensions. The main feature of GetDP is the closeness between the input data defining
       discrete problems (written by the user in ASCII data files) and the symbolic mathematical expressions  of
       these problems.

       GetDP is a command-line program. See Gmsh for a graphical front-end.

WARNING

       This man page does not describe the syntax of the input files: you should refer to the info documentation
       for  this  (e.g.  with info getdp). Up-to-date versions of the manual in various formats are available at
       http://getdp.info.

PROCESSING OPTIONS

       file
           is an ASCII file containing the problem definition, i.e., the structures  the  Texinfo  documentation
           will teach you to create. This file can include other files, so that only one problem definition file
           should  always  be  given  on  the  command  line.  The input files containing the problem definition
           structure are usually given the .pro extension (if so, there is no need to specify the  extension  on
           the  command line). The name of this file (without the extension) is used as a basis for the creation
           of intermediate files during the pre-processing and the processing stages.

       -pre resolution-id
           performs the pre-processing  associated  with  the  resolution  called  resolution-id.  In  the  pre-
           processing  stage,  GetDP creates the geometric database (from the mesh file), identifies the degrees
           of freedom (the unknowns) of the problem and sets up the constraints on these degrees of freedom. The
           pre-processing creates a file with a .pre  extension.  If  resolution-id  is  omitted,  the  list  of
           available choices is displayed.

       -cal
           performs the processing. This requires that a pre-processing has been performed previously, or that a
           -pre  option  is  given  on  the  same  command line. The performed resolution is the one given as an
           argument to the -pre option. In the processing stage,  GetDP  executes  all  the  operations  of  the
           selected  resolution  (such  as matrix assemblies, system resolutions, ...). The processing creates a
           file with a .res extension.

       -pos post-operation-id(s)
           performs the post-processing operations selected by the post-operation-id(s). This  requires  that  a
           processing has been performed previously, or that a -cal option is given on the same command line. If
           post-operation-id is omitted, the list of available choices is displayed.

       -msh filename
           reads  the mesh from filename rather than reading it from the default problem file name with the .msh
           extension appended.

       -msh_scaling value
           multiplies the coordinates of all the nodes in the mesh by value.

       -restart
           resumes time loop processing from where it stopped.

       -solve resolution-id
           same as -pre resolution-id -cal.

       -split
           saves processing results in separate files (one for each timestep).

       -res filename(s)
           loads processing results from filename(s) instead of from the default problem file name with the .res
           extension appended.

       -name string
           uses string as the default generic file  name  for  input  or  output  of  mesh,  pre-processing  and
           processing files.

       -adapt filename(s)
           reads adaptation constraints from filename(s).

       -order float
           specifies maximum interpolation order.

LINEAR SOLVER OPTIONS

       -solver filename
           specifies solver parameter file.

       [PETSc options]
           PETSc options (if GetDP was compiled with PETSc support).

LINEAR SOLVER OPTIONS

       -bin
           creates binary output files.  -v2 creates mesh-based Gmsh output files when possible

OTHER OPTIONS

       -check
           lets you check the problem structure interactively.

       -v int
           sets the verbosity level. A value of 0 means that no information will be displayed during processing.
           Higher values increase the amount of information displayed.

       -p int
           sets  the  progress  update  rate.  This  controls the refreshment rate of the counter indicating the
           progress of the current computation.

       -onelab name address
           communicates with OneLab server through socket.

       -version
           displays the version number.

       -info
           displays detailed version information.

       -help
           displays a message listing basic usage and available options.
