Parameter command for response variables.

Post by lorcancon » Tue Jul 22, 2014 3:18 am

Mike,

I have managed to assign nodal displacements to a parameter using the following command:

parameter $paramtag node $nodetag disp $DOF

However, I was wondering what other response variables can be assigned to parameters, and what their commands are. For example, how does one assign an internal element force (e.g. axial force) to a parameter? I think this should be possible because a method is given in the paper: "Summary of Work on OpenSees Reliability/Optimization/Sensitivity (2012)". However, the commands in this paper seem to be out of date. Is there a more up-to-date version of this paper? Could you reference me to the section of the source code which relates to assigning parameters to node /element responses?

Thanks in advance,
Lorcan.
