Re: [mcx-users] [MMCLab] Cyclic boundary condition

[Qianqian Fang]

hi Charly,

mmc does not support cyclic boundary. it only supports total absorption BC/Fresnel reflection BC and mirror BC

https://github.com/fangq/mmc/blob/01ed20bb9513bfee314582d7e2837286e2d1d51e/mmclab/README.txt#L113-L115

cyclic bc is very specific to slab-shaped domain. mmc's domain is more general to implement it.

if you need cyclic bc, and also higher shape accuracy, you may consider the SVMC mode of mcx, see my student Shijie Yan's paper

Dear Prof Fang and MMCLab users,

I am starting to use MMCLab and wonder if it's possible to model a semi-infinite medium using cyclic boundary conditions (like the cfg.bc parameter in MCXLab)?

Yours sincerely,

Charly

Thanks very much for your explanation. It will be very useful for my work.
