MBDYN(1) General Commands Manual MBDYN(1) NAME mbdyn - MultiBody Dynamics analysis system. SYNOPSIS mbdyn [-E [exceptions]] [-e ] [-f input-file] [-H ] [-h ] [-l ] [-N threads-number] [-o output-file-prefix] [-P ] [-p ] [-R ] [-r ] [-S sleep-time] [-s ] [-T ] [-t ] [-v ] [-W new-working-dir] [-w ] [in- put-file[...]] DESCRIPTION mbdyn is a multibody analysis tool released under GPL <http://www.gnu.org/licenses/gpl.html>. It solves initial value problems for multibody, multidisciplinary systems including, but not limited to, the mechanical and aeroservoelastic fields. The most important and most widely used options are -f to pass the name of the input file, and -o to pass the name of the output file. OPTIONS -E, --fp-mask [exception[,exception]] Mask some floating point exceptions; supported values of exception are invalid, divbyzero, overflow. -e, --exceptions Do not trap (some) exceptions, to ease debugging. -f, --input-file <input-file> Read model and analysis data from file input-file; default is stan- dard input. The current working directory is set to the path to in- put-file (see chdir(2) for details). As a consequence, any sub-file included using the include directive needs to be referred to either with the full path, or relative to the folder where input-file re- sides. -H, --show-table Shows a list of the symbols defined in the symbol table of the math- ematical parser, with their value. -h, --help Displays usage information. -l, --license Show licensing info. -N <threads-number> Number of threads used in multi-threaded simulations (an integer). When threads-number is auto the number of available cores is auto- detected. -o, --output-file <output-file-prefix> Write results to files with prefix output-file-prefix (extensions are content-dependent); default is input-file, if any, or "MBDyn". If output-file-prefix is a directory, the output file will have the name of the input file, but it will be placed in that directory. -P, --pedantic Issue pedantic warnings (more occurrences raise the level). -p, --parallel Run in parallel mode (only if compiled with MPI). -R, --no-redefine Do not allow symbols in the mathematical parser to be redefined. -r, --redefine Allow symbols in the mathematical parser to be redefined; useful in conjunction with -t. -S, --sleep [rank=<r>,]<sleep-time> Sleep sleep-time seconds before starting the simulation. When run- ning in parallel, if sleep-time is prefixed by rank=<r>, only the process with rank r (0 to number of processes - 1) will sleep. -s, --silent Reduce verbosity (more occurrences reduce the verbosity level fur- ther). -T, --no-same-table Do not preserve the existing mathematical parser symbol table when running multiple analyses in the same run. -t, --same-table Preserve the existing mathematical parser symbol table when running multiple analyses in the same run (e.g. by issuing multiple input files on the command line). It may require -r to allow redefinition of symbols. -v, --version Show version and exit. -W, --working-dir <new-working-dir> Use new-working-dir as working directory instead of the current one. -w, --warranty Issue a "warranty" message.
