Region Rayleigh Damping Error

[structural10]

I am using the region command to assign Rayleigh damping to my models. When I try to assign damping to my entire model using the "-ele all" option, OpenSees does not apply damping to any of the elements. I am using the displacement-based fiber beam-column elements (dispBeamColumn). Also, does the order of the assignments in the region command matter? (e.g., "-rayleigh ... -ele ..." or "-ele ... -rayleigh ..."; I tried both ways with "-ele all" but neither worked) I do realize that using the "rayleigh" command after defining my model will also assign damping to the entire model, but using the region command is much more convenient in my context. Thanks.

the documentation is incorrect .. all is not an option .. use the range instead.
