All the fields considered (forces, displacements, deformations, deformations, stresses, flows) are expressed in cylindrical coordinates with the following convention on the order of the components:

next radial component \(r\) axial component next \(z\) next tangential (or circumferential) component next \(\theta\) Example: \(({u}_{r},{u}_{z},{u}_{\theta })\) \(({f}_{r},{f}_{z},{f}_{\theta })\)

The mesh is located in plane \((r,z)\), the symmetry of revolution taking place around the \(\mathrm{Oz}\) axis. Triad \((r,z,\theta )\) is oriented in the anticlockwise direction.
