Finite Element Quadrature of Regularized Discontinuous and Singular Level Set Functions in 3D Problems
Regularized Heaviside and Dirac delta function are used in several fields of computational physics and mechanics. Hence the issue of the quadrature of integrals of discontinuous and singular functions arises. In order to avoid ad-hoc quadrature procedures, regularization of the discontinuous and the...
