Hi guys,
I'm using Meep on Ubuntu 10.04 and the installation went fine.
Now I used the tutorial from the Meep Wiki and put this code in a ctl file:
[code]
(set! geometry-lattice (make lattice (size 16 8 no-size)))
(set! geometry (list
(make block (center 0 0) (size infinity 1 infinity)
(material (make dielectric (epsilon 12))))))
(set! sources (list
(make source
(src (make continuous-src (frequency 0.15)))
(component Ez)
(center -7 0))))
(set! pml-layers (list (make pml (thickness 1.0))))
(set! resolution 10)
[/code]
Then I entered:
[code]
(run-until 200 (at-beginning output-epsilon) (at-end output-efield-z))
[/code]
This returned the following error messages:
[code]

Some deprecated features have been used. Set the environment
variable GUILE_WARN_DEPRECATED to "detailed" and rerun the
program to get more information. Set it to "no" to suppress
this message.
[/code]
What is the problem here and how can I solve it?
Thanks a lot!
Stefan
