lame quesion about kinematic couplings

[dkakth]

Hello colleagues

On a part I have a different load scenarios, they involve different node sets, which overlap in some cases.
I have defined refrence nodes and used kinematic couplings to connect to those node sets.
The problem is at one sceniario i put load on a refrence node but the unloaded set is still coupled to another RP. Does this distorts displacement results ?

Is there a way to "turn off" , surpress or disable some of the kinematic couplings , or for each load scenario i need to make a separate model which contains only the couplings used/needed ?

thanks and salute

It’s not possible to deactivate coupling constraints during the analysis. You can try replacing these constraints with connectors.
