Hi All,

My model (.inp) in ABAQUS has two parts.Its a cylinder with inside lumen.I am applying Boundary Condition at outer vessel (keeping it fixed at both ends) and load (Pressure) on inside lumen. Errors I am encountering are

1) 53776 elements have missing property definitions. The elements have been identified in element set ErrElemMissingSection.

2) THE NLGEOM FLAG MUST BE SET ON THE *STEP OPTION IF A HYPERELASTIC, A HYPERFOAM, OR A FABRIC MATERIAL IS USED.

(My material is Hyperelastic>Mooney Rivilin>Coefficients, step is General,static and I am not creating any section under the Property module)
