Re: [Meep-discuss] doubt regarding subpixel averaging behaviour
Dear Filip, ok, thanks for your answer. I will try to check if this affects the results or the behaviour of the full simulation. Pablo.

[Meep-discuss] doubt regarding subpixel averaging behaviour
Dear meep users, I have encountered a strange behaviour of subpixel averaging when running meep-mpi. Working at one node with 8 processors, if I do the simulation with 7 processors or less, subìxel averaging performs as it should be, but if I choose the 8 processors it won't work even eps-averaging is set to true. Does someone know why this happens? Thanks in advance, Pablo. ___ meep-discuss mailing list meep-discuss@ab-initio.mit.edu http://ab-initio.mit.edu/cgi-bin/mailman/listinfo/meep-discuss
[Meep-discuss] Error installing meep-1.3
Dear meep users, I'm trying to install meep-1.3 in OS X 10.6.8 but it's failing. I'm using Guile 1.6 via macports, harminv 1.4 and libctl 3.2.2 from source. The error occurs when making meep, at meep_wrap.o and it says that most 'scm_' variables are not declared, for example, this is the first of the long list of errors I get: CXX meep_wrap.o meep_wrap.cxx: In function ‘char* SWIG_Guile_scm2newstr(scm_unused_struct*, size_t*)’: meep_wrap.cxx:821: error: ‘scm_is_string’ was not declared in this scope meep_wrap.cxx:823: error: ‘scm_to_locale_string’ was not declared in this scope I don't really know how I can solve this and I did not have any problem installing previous versions of meep. Thanks in advance, Pablo. ___ meep-discuss mailing list meep-discuss@ab-initio.mit.edu http://ab-initio.mit.edu/cgi-bin/mailman/listinfo/meep-discuss
[Meep-discuss] Differential Scattering Cross Section
Dear meep users, I'm interested in calculate the differential scattering cross section of a metal nanoparticle in meep. By now I understand reasonably well how to calculate the cross section, but not sure how should I calculate the differential scattering cross section. Any help would be much appreciated. Thanks in advance, Pablo. ___ meep-discuss mailing list meep-discuss@ab-initio.mit.edu http://ab-initio.mit.edu/cgi-bin/mailman/listinfo/meep-discuss
[Meep-discuss] epsilon-input-file doubt
Dear Meep users. I want to simulate a silicon structure that includes material dispersion. Then I will modify this structure in a series of simulations but keeping the changes done before, so I want to use the epsilon-input-file funcition. My doubt is, ¿does the eps.h5 file keep the susceptibilities that were defined for the first simulation in the silicon structure when epsilon-input-file is used? Thanks in advance.

[Meep-discuss] silica dispersion model
Dear meep users. I need to use the dispersion model for fused silica in my simulations. Since these physics are quite new to me, I'm not sure how I should calculate the parameters for the lorentzian model. Could someone point me in the right direction or tell me about any literature I could check? Thanks in advance.
