ProductsAbaqus/Standard ## ConventionsCoordinate 1 is r, coordinate 2 is z. Referring to the figures shown in Choosing the element's dimensionality, the r-direction corresponds to the global X-direction in the $\theta ={0}^{\circ}$ plane and the negative global Z-direction in the $\theta ={90}^{\circ}$ plane, and the z-direction corresponds to the global Y-direction. Coordinate 1 must be greater than or equal to zero. Degree of freedom 1 is ${u}_{r}$, degree of freedom 2 is ${u}_{z}$. The ${u}_{\theta}$ degree of freedom is an internal variable: you cannot control it. |
