Hi , For Space Frame ( 3D) analysis , what should be the member releases ( Release Mx , My , Mz) , i tried defining truss(3D) for members but it causes a error in output , " **WARNING - THERE WERE MORE THAN 12 DOF WITH ZERO STIFFNESS "
I think the Space frame members should be release at the starting node and end node of the member .
kindly advice ,
