Good Day Everybody,
This is my first post. I have been using ESPResSo for a month now. I have both version 3.2.0 and 3.3.0(using this) with LB components, mpi, gpu, cuda, fftw3 compiled in.
I have a few quick questions.
Is there a way to use lb fluid in slitpore? While I tried this the simuation gave error that lbboundary does not accept the slitpore parameter.
What is best way to make two point charges kept ~10- 50 molecular distance unit apart to interact electrostatically? Which algorithm should be applied?
I am simulating a system where I have lined an array of negatively charged particles on the boundaries of the simulation box ( I realized I could not use charged plates because constraint plate works only in z direction, or is there a better way to do this?). There are a few charged molecules in the box, but they do not move at all during simulation as if they are not affected by any electrostatic field at all. I have tried p3m, mmm2d and played around with the arguments, without luck.
Where can I read how p3m, mmm2d work? How to implement has been very well explained in documentations, but what they do in the back end was not really clear to me.
Is there a way to simulate lb fluid in only specific custom defined boundaries? Like a U-tube.
Follow-up question- if I fix particles in any geometry I want (u-tube like) and then simulate lb fluid, will this work? Will the fluid see the particles as a boundary and move along that in u tube?
I am sorry if the questions are vague, please let me know. If there is a way to solve the above mentioned problems by changing the source code, I would like to give it a try. I have already changed one file in source to meet my requirements (it will not affect simulations, only the output in vtk format, the way was required by me).
Thanks for the help.
