Dear MEEP users,
My MEEP codes are running slower after I upgraded to Ubuntu 16.04 from
14.04. Earlier if a code took, for example, 1 minute to run, the same code
now takes 10 minutes to run.
Does anyone else have this problem?
There are no errors, but the subpixel averaging is now taking much long
Hello,
Thank you for your reply.
Currently, the code is without multi-processing. With multiprocessing with
2 cores, time needed is reduced by little over half.
I do use hdf5 export, but only at the end and the time needed is negligible.
The problem is at the "initialization", which seems to run fo
No. disabling subpixel averaging also does not help. The time needed to run
remains the same.

Dear MEEP users,
The problem of MEEP running slow is still unresolved for me.

Dear all,
Sorry for bothering again with the same question.
I too have installed Meep in 17.04 ubuntu using the shell script and
everything works fine. But the problem of increase in time when using
material-function still exists. Will it be fixed once PyMeep is officially
released?
Here is the ori
Hi all,
Can someone provide an example as to how to define the geometry in PyMeep
using meep.material_function?
For the straight waveguide example if I define the waveguide using a
function, how to include it in defining the geometry?
Currently, I wrote
import meep as meep
import numpy as np

Hi all,
I am trying to use epsilon_input_file in PyMeep to define an arbitrary
anisotropic geometry. But as per the document the HDF5 file can have only
one dataset corresponding to a scalar dielectric function.
So I tried to load the files individually having data for the epsilon_diag

Hello,
I think it is because a Gaussian function can not be properly defined in
Meep. If you take a Gaussian pulse or beam and propagate it in Meep you
will see that the dispersion/diffraction given by meep is not the same as
that should be from theory. So this should be accounted when you add othe
Dear all,
What is the correct syntax to use strength in the pml class in python meep?
I wrote
pml_layers = [meep.PML(thickness=pml, direction=meep.X),
meep.PML(thickness=10, strength=2.0, direction=meep.Y)]
which gives an error
TypeError: __init__() got an unexpected keyword argument 'strength

I am getting *division by zero* error while running a script for time=0 in
