In FEM, which option is not correct about the Lagrange family of triangular elements? Correct Answer Dependent variables and their derivatives are continuous at inter-element boundaries
In Lagrange family elements the nodes are regularly placed everywhere on the grid i.e., they are uniformly spaced. The location of the terms in Pascal’s triangle gives the location of nodes in elements. Thus, Pascal’s triangle can be viewed as a triangular element. The derivatives of dependent variables are not continuous at inter-element boundaries. 2nd-degree polynomial corresponds to 6 noded triangles.
