GetDP - a General environment for the treatment of Discrete Problems
SYNOPSISgetdp [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://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 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.
-pospost-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).
-resfilename(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.
-adaptfilename(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.
