operate on it easily and save it to a desired format by itself,
without even needing to
use the parallel I/O. What do you think of that ?

Hi,
In the program I am developping now I have to be able to output a
given type of field (Ex, Hz, ... ) into
VTK files. It is a format useful for 3d-data storage and very
efficient for their 3d-visualisation.
As for now I am doing it with first outputtting the field through the

double gamma, double delta_epsilon, double energy_saturation);
There are some examples available in tests/known_results.cpp and
tests/symmetry.cpp.

Hi,
I would like to know how to use the perfect metal in the C++
interface. I can not find it in the documentation.
Do I have to return some specific value from the eps function or it is
done in a different way ?

the fact that neither your structure

Hi,
Is there a way to influence the field in meep in a specific location?
I would like to set to zero all the field values in some specific 3d
box inside the calculation volume.
There is function fields::zero_fields() but it sets to zero all the
calculation volume.
Is there a way to do it for a

double e=ex+ey+ez+hx+hy+hz;
Is it optimal ? It is still not as fast as the algorithm in Fortran I
mentioned earlier.
Thank you,

It seems to be just a problem of FIELD output in HDF while using MPI.

Hi,
I am using meep in MPI.
I can not find a logical way to synchronize my myself between all

In mpi should be a command like mpi_barrier which
on this forum (Unable to output fields to HDF in MPI meep.)
seems to be solved. When using real fields I can output
HDF fields in MPI mode without problems.
Thank you.

Hi,
How can I use the metallic boundary condition in the C++ interface ?
With structure s(v, eps, pml(1.0)); I create a PML layer but in
Scheme interface it is also possible to create a metallic boundary.
How to do the same in C++ ?
Thank you for any help,
