Thank you! I am new in FE stuff. By "needed" I meant that why they exist? If there is wedge option in abaqus that I thought it has to be good for something.
Hello everybody!
For 2D FE models ABAQUE generate meshes containing 3-nodes and 4-nodes elements. But for 3D combination of tetrahedral (pyramid), hexahedral (brick) and wedge elements can be found.
Why are 3 elements types needed for 3D meshes rather then just pyramid and bricks?
Why in 2D...
