xfemm

I know this is an old thread (as are most of the threads here) but I was about to post about this very same issue myself. I've noticed that there seems to be a significant difference between how FEMM and xfemm treat overlapping segments; in FEMM ... [More] , overlapping segments are automatically merged, deleted, and split in such a way that you need never (or, at least, I never) worry about overlapping segments; the concept was entirely new to me when I started using xfemm. I've been reading through the IABC... [Less]

There's a very useful wizard in FEMM, "Create IABC Open Boundary," which automatically constructs high-order asymptotic boundary conditions using the problem geometry and user inputs. Is this tool available somewhere in xfemm? I tried searching the ... [More] xfemm source directories for "ABC" as well as for one of the idiosyncratic permeability coefficients, but all that returns is init.lua, which I believe is FEMM source. It seems rather straightforward (albeit time-consuming and prone to transcription error)... [Less]

Sounds good. Thank you for all of the work that you've put into this project!

I was listening, if it helps, but unfortunately too busy to help at the moment, and have experience, or access to a mac. At some point I can see if I can merge your changes with the main code.

Well, I got it all to compile. It was a massive pain. I modified several include directives and compilation options as described above (trivial modifications, I suspect) but also commmented out a couple of FPU-related lines (potentially more ... [More] consequential?) since Apple purportedly does not support the setting of FPU flags. I've attached my whole build directory (which includes the binaries) here. I was talking to myself on this forum - perhaps there isn't a lot of Mac interest here - but I thought... [Less]

Almost forgot to mention that the very first issue I had was with sincos when compiling femmcomplex.cpp: Error using mex /Users/rapmaster/Documents/MATLAB/xfemm_linux64/mfemm/../cfemm/libfemm/liblua/femmcomplex.cpp:629:5: error: use of undeclared ...
