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://www.geuz.org/getdp/.

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

       -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.
