Cylindrical basis vectors
WebIn the current configuration Abaqus formulates the equations in terms of a fixed spatial basis with respect to the axisymmetric twist degree of freedom. The basis vectors convect with the material. However, because of the axisymmetry of the model in the deformed configuration, these vectors can be defined at Θ = 0 as WebMar 14, 2024 · The three-dimensional cylindrical coordinates (ρ, ϕ, z) are obtained by adding the motion along the symmetry axis ˆz to the case for polar coordinates. The unit …
