Partial damping through regions

[hismaimaimai]

Hi everyone,

I'm using zero length elements to define the plastic hinges in a structure. I don't want their stiffness to contribute to the damping matrix so when I define them I use "-doRayleigh 0" (which is the default any way). Later on my script I define the Rayleigh damping using regions, but the zero length elements are included in those regions.
