I'm interested in looking at some problems that involve time harmonic versions of Maxwell's equations in looking around at how these have been approached in finite element models in the past, I've run into a few issues:
The first of which is how to represent a curl operator. Presumably it might be best to add the functionality, perhaps based on existing gradient functionality? I suppose that there are workarounds using the existing API, but if they're part of an equation I suspect that might get more complex than desirable. In taking a look at solving time harmonic versions of maxwells equations to look at volumes where cells can have both permittivity and conductivity, I ran across an earlier discussion about working with complex values: http://comments.gmane.org/gmane.comp.python.fipy/977 In that it was suggested that one could split each equation into a pair of coupled equations. What I'm not entirely certain about is how to go about this if the variable for the diffusion terms employed should end up as complex values. Any suggestions or comments would be appreciated. -- James Snyder Biomedical Engineering Northwestern University http://fanplastic.org/key.txt ph: (847) 448-0386 _______________________________________________ fipy mailing list [email protected] http://www.ctcms.nist.gov/fipy [ NIST internal ONLY: https://email.nist.gov/mailman/listinfo/fipy ]
