5. C modeling#
5.1. Characteristics of C modeling#
Using QUAD4 elements
5.2. Characteristics of the mesh#
Number of knots: 4
Number of meshes and types: 3 MECPQU4
Modeling in plane constraints: C_ PLAN
Loading and boundary conditions are modelled by:
DDL_IMPO: (Node NO1 DX = 0, DY = 0)
(Node NO2 DY = 0)
(Knot NO4 DX = 0)
forces imposed on nodes \(\mathrm{NO2}\) and \(\mathrm{NO3}\).
