1. Is it possible to record the stresses and strains at the gauss points for a shellMITC4 element.

2. Is there a command to output the Mass and Stiffness matrices.

Thanks

I have been able to output the forces at the nodes of ShellMITC4 elements. 24 Forces are output per element corresponding to 6 forces at each of the element's 4 nodes. Is it possible from this output to determine the stress state in the element such as at the Gauss points or to interpolate from the ...

Try:

recorder Node -file eigen1.out -node all -dof 1 2 3 "eigen 1"

with the brackets around the "eigen #" portion

Hello, Using the following line to record the forces in the shell elements of a model I get an output which includes three different lines. In what order does OpenSees output the forces for shell elements, or rather which force does each line represent. Thanks recorder EnvelopeElement -file allEllgl...
