“Since grid-cell discretisation possesses little structure, these schemes can at best be first-order convergent.”
“In order to speed up this process are performed with first-order discretisation.”
“The finite element method is applied for discretisation of a structure and mathematical programming is used for the numerical solution to the problem.”
“However, they were able to construct frames that were actually tight, by performing exact discretizations of integrals, by using appropriate cubature points.”
“Numerical methods for partial differential equations use different discretizations of space and time and have different mathematical properties, like convergence and accuracy.”
