Dear all,

I have modelled a 3D canopy structure with solid elements which will be acting as the fabric. I am having issues running the model as it is coming up with issues as shown in the subject.

The solid is a hyperbolic shape as shown in purple. The rest are CHS sections.

Any help would be appreciated.

Thanks
