1. Discretization#
1.1. Degrees of freedom#
Modeling |
Degrees of Freedom (at each vertex node) |
AXIS |
DX: corresponds to the radial displacement DY: corresponds to the longitudinal displacement |
D_ PLAN |
DX: move next X DY: next move Y |
C_ PLAN |
DX: move next X DY: next move Y |
1.2. Support mesh for stiffness matrices#
The support cells of the finite elements can be triangles or quadrangles. The elements are iso-parametric.
