Node-Tet constraint with Penalty zero mass error
Posted: Tue Sep 19, 2017 5:57 am
Hi,
I created a node list that is common between beams with and without stirrup reinforcement. When i ran the beam with all reinforcement, it went smooth as it was in the older versions. When i dont define all beam elements for stirrups, some of the nodes in the rebar node list become completely disconnected, in previous versions this was running without problems. After updating i get this message
Found zero nodal mass in node-tet constraints (Penalty).
Check mass in tet list.
The penalty based on time step on Youngs modulus dont work, the only one that works is with direct stiffness as an input. Is it ok to change this from Error to warning and allow the program to contineue
