femaxx_driver
program.
femaxx_driver
is a program for computing a few of the lowest eigenvalues and eigenvectors of an accelerator cavity given by a tetrahedral mesh. The computation can be customised using a variety of command line options.
The basic operation of femaxx_driver
is the following:
femaxx_driver
prints some basic status information to stderr
. In addition a more verbose, uniquely named log file is generated.femaxx_driver
is an MPI programm that accepts a variety of command line options. To print a list of all options, start femaxx_driver
with the -h
option. Usally this is accomplished with the following command.
mpirun -np 1 build/release/examples/femaxx_driver -h
femaxx_driver
requires the --mesh
and the --sigma
parameters to be set. All other parameters are optional.
A typical command for running femaxx_driver
would be
mpirun -np 2 build/release/examples/femaxx_driver --mesh=/meshes/cop40.ng \ --sigma=1.5
femaxx_driver
reads the mesh information from the HDF5 file /meshes/cop40
.ng and then computes 5 eigenvalues near the specified shift value 1.5 together with the corresponding eigenvectors. Note that shift =1.5 corresponds to a eigenfrequency f of about 58.43 MHz, using the equation .
