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 dis-
       cretize 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 geo-
	   metric 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	avail-
	   able	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 exe-
	   cutes 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-opera-
	   tion-id(s). This requires that a processing has been	performed pre-
	   viously, 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 de-
	   fault 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.

       (http://getdp.info).

       The full	documentation for GetDP	is maintained as a Texinfo manual.  If
       the  info  and  getdp programs are properly installed at	your site, the
       command

	      info getdp

       should give you access to the complete manual.
