I tried your approach.
But because I am on the other part of the globe - mine is 11/21/2020 version of OpenSees. (Shouldn't be a problem)
But I get this error for all elements:
"getRayleighDampingForces" is not a member of "ForceBeamColumn2"
like this I am getting errors that most of the elements dont have this method.
All of them include "Element.h" and "Element.h" has this method in place....
I don't know. Kindly help me resolve this.
one more error -
"Vector::addVector': function does not take 2 arguments"
this is also repeating...
I followed the same process you have shown in your video. It's compiling !
One reason the compels me to use OpenSees is the support that we get from the developers directly. They give time and help for others to benefit from their software. This is the unique feature of this project.
Thank you for your help.
