Mixed finite element methods solve a PDE using two or more variables. The theory of Discrete Exterior Calculus explains why the degrees of freedom associated to the different variables should be store...
When parametric functions are used to blend 3D surfaces, geometric
continuity of displacements and derivatives until to the surface
boundary must be satisfied. By the traditional blending techniqu...
