Hi all,
I'm enjoying playing with meep just doing 2D simulations. I'm
working up to simulating things in conductive environments and have
managed thanks to some pointees from this list and Stephen's invaluable
assistance, to get a good number for this dielectric constant. I've
noticed that when I use pure dielectrics the software is pretty quick
but as soon as I have a complex dielectric is slows down considerably.
Simulating a 10x20m space, filled for the bottom 14m with seawater
(epsilon=81, conductivity=4S/m) (where my scale 'a' is 1m making this a
10x20 simulation in meep) with a single current source 1m above the
water surface, is taking ~6000s to complete (not the fastest computer on
the block). Doing the same simulation with a block of pure dielectric
instead of seawater (epsilon-81) takes only 75s
Is the slowdown due to the use of complex fields necessitated by the
complex dielectric or am I doing something stupid in trying to use a
comparison of this type ?
all the best
Chris
