[mcstas-users] curved guide

[Peter Link]

Dear friends,

just to avoid some double developpment: to my knowlegde there are the 
following components or ways to simulate a standard curved neutron guide:

Bender; allows for different reflectivities on top/bottom inside 
outside; can have multiple channels; but behaves geometrically as 
straight guide element (mcdisplay, coordinates of subsequent elements)

Guide_curved; only one reflectivity definition for all sides, 
geometrically correct definition

polygon of Guide_gravity elements; allows for a polygonal approximation 
only, has numerous options

Having a number of truly curved guides in my simulations I would prefer 
to have a component, which has the possibilities as it has Bender or 
Guide_gravity but is a geomentrical correct implementation of truly 
curved guide. If someone has done this or can tell me where I have 
overseen it, I would be grateful.

Bets regards

Peter
