Re: [ESPResSo-users] How to adjust reflecting constraints in version 4.0.1

[David Sean]

Hi David,

I am trying to understand what you mean by 'reflecting'. I tried
searching the docs for 'reflect' but could not find it mentioned in
the context of a constraint. Constraints are described here:
http://espressomd.org/html/doc/constraints.html and there is a sample
script /samples/constraints.py that you can look at.

There used to be a reflect_particle() function for shape-based
constraints, did you mean that? Can you describe what you are trying
do, i.e, is this for particles, or an LB fluid... or both?

David
