Displays extra info.
Displays software version, and source control information if applicable.
Displays help information about the available command-line options for the executable.
Override a parameter (or define a new one) specified in the XML file.
Override a solverinfo (or define a new one) specified in the XML file.
Determines the output format for writing Nektar++ field files that are used to store, for example, checkpoint and solution field files. The default for
is an XML-based format, which is written as one file per process. If Nektar++ is
compiled with HDF5 support, then an alternative option is
Hdf5, which will write one
file for all processes and can be more efficient for very large-scale parallel
When using a fully-Fourier expansion, specifies the number of processes to use in the x-coordinate direction.
When using a fully-Fourier expansion or 3D expansion with two Fourier directions, specifies the number of processes to use in the y-coordinate direction.
When using Fourier expansions, specifies the number of processes to use in the z-coordinate direction.
Prints detailed information about the generated partitioning, such as number of elements, number of local degrees of freedom and the number of boundary degrees of freedom.
Partition the mesh only into the specified number of partitions, write to file and exit. This can be used to pre-partition a very large mesh on a single high-memory node, prior to being executed on a multi-node cluster.
Forces the use of METIS for mesh partitioning. Requires the
option to be set.
Forces the use of Scotch for mesh partitioning. If Nektar++ is compiled with METIS support, the default is to use METIS.
Hdf5-format mesh in parallel to avoid one single thread runs out of
memory in serial partitioning.
Set the starting time of the simulation. This overwrites the time in the file-type initial condition.
Set the starting number of the checkpoint file. This overwrites the checkpoint number in the file-type initial condition.
