2D modeling elements PLAN
3.2. Characteristics of the mesh#
Number of knots: 3382
Number of meshes and types: 2000 meshes including 400 QUAD8, 400 QUAD9, 400 QUAD4 and 800 TRIA3.
The mesh includes 4 squares SQU8, SQU9, SQU4, and STR3 meshed respectively with elements QUAD8, QUAD9, QUAD4, and TRIA3. Each square is discretized with 20 elements along X and Y.
