On the Use of Discrete-continual Finite Element Method with Unstructured Meshes

The field of application of discrete-continual finite element method comprises structures with regular (in particular, constant or piecewise constant) physical and geometrical parameters in some dimension (so-called “basic” direction (dimension)). Considering problems remain continual along “basic” direction while along other directions mesh approximation is performed. Algorithm of computing of local stiffness matrix of discrete-continual finite element with quadrangular cross-section and different integration schemes is presented. Constructing of global stiffness matrix with the use of adjacency matrix and several numerical samples are considered as well.
