A Complete Example for multipacting field level scan

Some Explanations
The following lines show the number of elements and number of DOFs in the computation:
The following lines show the memory usage:
Maximal per-core estimated memory 451 MB Aggregated estimated memory 875 MB Maximal per-core estimated memory if OOC 184 MB Aggregated estimated memory if OOC 365 MB
If the Maximal per-core memory is larger than what is available, user should either increase the number of cores in the computation or use other options such as Out-of-core (OOC) solver. Note that it may not be good to use excessively large number of cores in the computation (in fact, it may hurt performance or it may fail to get results if doing so). It is often a good idea to have a few thousand elements per core in the parallel computations.
The following lines show the resulting eigen frequencies.
Number of converged eigenpairs = 2 eigenvalue: 2.726061596672462e+03 Frequency: 2.491200411267457e+09 Residual: 2.54e-11 eigenvalue: 3.545447315320415e+03 Frequency: 2.841033486606133e+09 Residual: 1.25e-09
Note that the residual of the eigenpair should be reasonably small to be a good solution.
