Hi
I appreciate this approach for betterment of OpenSees...

I have only two requests

1. Access of stiffness matrix during analysis, be it static or dynamic.

2. Inclusion of Caughey damping, for dynamic analysis to provide more control over damping.

thanks

gopal

Hi,

Unitless representation of fiber coordinates in the recorder command would provide a considerable amount of reduction in the number of output files.

Thanks.

reference post: "Number of maximum open files limit"

hi,
more explenation about matrial (e.g. concrete01 02 03 04 and steel01 02 reinforcing steel ) and application of them in different problom and diffrence of them.
more explenation about fiber section and mesh sizing of fiber and about nonlinear beam column and number point of intgration because it affected answer.
some verifing cases like manul of IDARK
and technical manual about opensees

1-how can we use shell element with fiber sections in na?
2-a simle approach to achieve damage index.
