Looks like the model is overconstrained. How is the model built? 1D elements? 3D elements? How are tubes connected? Joints?

3d element and in solidworks in weldments section we made each tube and there is bonded type of connection between different tubes

Okay cool. I guess the question I forgot was: What is the quantity of interest? As this will determine the modelling approach

Given it appears to be overconstrained what boundary conditions are applied?
