Thank you so much for your open source software. I appreciate it very much.
May I ask a question. I am studying the channel propagation effect of furniture. I would like to simulate RCS of furniture (such as chair and desk) in channel propagation using FDTD. Is it suitable for simulation of wireless channel propagation. I would like to compare results using measurement data and simulation using FDTD. How much memory and which user interfaces are necessary to run your software and how can I modify and update it for my model. Please, answer and guide me.
Thank you so much in advance.

Thanks for the feedback.
I am studying the channel propagation effect of furniture.
What is channel propagation? You mean a wireless channel and how it is affected by furniture??
How much memory and which user interfaces are necessary to run your software and how can I modify and update it for my model. Please, answer and guide me.
I can't say anything about memory for your problem, but FDTD is quite efficient with memory.
The interface to openEMS is Matlab or Octave. I think you should start running some Tutorials.
Especially this one: http://openems.de/index.php/Tutorial:_M ... ss_Section
To include your furniture you can use the STL or PLY import functions, run in Matlab/Octave:

Code: Select all

help ImportSTL
help ImportPLY

Thank you so much for your reply.
I can run your tutorial.
Yes..I am studying for wireless communication. So, I would like to know the effect of furniture in indoor propagation channel.
Okay, I will try your suggestions.
I would like to ask how to define and import the object. How can I do?
However, I also don't know the following applications.

Dependencies

Libraries used by openEMS:
CSXCAD: Part of the openEMS project. Author: Thorsten Liebig
tinyxml: A small and tiny xml parser written in C++. TinyXml website
fparser: Function parser library for C++ fparser Website
boost: http://www.boost.org/
hdf5: Hierarchical Data Format http://www.hdfgroup.org/
vtk: The Visualization Toolkit (VTK) http://www.vtk.org/
mpi: Message Passing Interface. mpich2 or Open-MPI


Thank you so much again.

Sincerely,
Maw.
