Running the code

The program may be executed by typing
oofem [option [parameter]] ...
on the command line prompt with the following command line options:

• -f string
  oofem input file name, if not present, program interactively reads this parameter.
• -r int
  Restarts the analysis from given solution step. The corresponding context file (*.osf) must exist.
• -rn
  Turns on the profile renumbering. Default is off. It will not work in parallel mode.
• -ar int
  Restarts the adaptive computation from given solution step. Requires the corresponding context file (*.osf) and domain input file (*.din) to exists. The domain input file describes the new mesh, its syntax is identical to syntax of input file, but it does not contains the output file record, job description record and analysis record.
• -qo string
  Redirect the standard output stream (stdout) to given file.
• -qe string
  Redirect standard error stream (stderr) to given file.
• -context
  Forces the creation of context file for each solution step.

The parallel version uses the MPI (Message Passing Interface) standard for message-passing communication. Thus, to execute POOFEM program, users must know the procedure for beginning MPI jobs on their selected computer system(s). For instance, when using the MPICH implementation of MPI and many others, the following command initiates a program that uses eight processors:
mpirun -np 8 poofem program_options
