Dear Nizamov, Thank you so much for your reply. I guess you are talking about the two ways of interaction with MEEP. 1) low level C++ interface, i.e. the test programs. 2) high-level Scheme script.
My question now is how I can add a few more grammar rules to the Scheme script. I am going to define an active region between the cavities and solve the additional equations based on this paper: Active materials embedded in photonic crystals and coupled to electromagnetic radiation (Pater Bermel et al) If I would like to expand the Scheme scripting language, how would I approach this? I thought there is a parser to parse the script but apparently the Scheme script is interpreted directly and the structure objects are built from there. How can Scheme interpret my new class "activeRegion"? Where do I define the grammar rule? Do I simply define a class named "activeRegion.cpp" and scheme will recognize it and interpret and build the activeRegion object nicely? Thank you so much for your reply. -- Bin Huang (Bryan) MIT Graduate Student '10 Computation for Design and Optimization (+65)98947649 ________________________________________ From: Nizamov Shawkat [[email protected]] Sent: Thursday, September 09, 2010 4:54 AM To: Bin Huang Cc: [email protected] Subject: Re: [Meep-discuss] MEEP development main() is supposed to be the part of the user written program (meep core is just a library). So you are supposed to implement main() on your one, specifying all simulation details step by step. Look through meep test programs to find usual sequence of simulation setup.
