Hi,
Together with the Stokesian Dynamics integrator I implemented a BD
integrator as well.
It should work, if you compile with the SD enabled, you should be able
to use
part 0 pos 0 0 0
setmd time_step 0.1
setmd sd_visc 1
setmd sd_radius 1
integrate_sd 1
puts [part 0 print pos]
If you cannot meet the requirements for SD (CUDA etc.), I could try to
patch it, that BD can be compiled without SD.
Kind Regards,
David
