Hi all,
I've created a cylinder and applied boundary conditions and pressure in the inside of the cylinder (cylinder is expand due to the pressure inside of it) (the model also is created by nodes and elements using shell 181). the analysis works until I add a frame to the inside of the cylinder in order to support the cylinder from expanding. after adding the supporting frame (which is also created by nodes and elements), I kept receiving "There is at least 1 small equation solver pivot term. Please check for an insufficiently constrained model" error message.
I don't know to con constraint or unconstraint the model!
Any help would be great.
Thanks,
Azadeh
