WebOct 15, 2011 · We solve Navier–Stokes equations using isogeometric analysis. We examine different discretizations of the pressure and velocity spaces. Stability may be achieved by means of knot refinement of the velocity space. Optimal error convergence is found when using knot refinement of the velocity space. All examined discretizations perform … Web2024 Refinement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories 8.7 . 8.2.5 Notation keys and completeness information .

Based on the difference between any two consecutive knots, a knot vector can be categorized either as a uniform or as a non-uniform vector. If … Webinvolves the development of a new knot sequence t,and a new set of control points R] which define the same curve. The subdivision process is driven by a knot refinement, the adding of new knots to r, and this is defined by Definition 2.1. Let r = (To, . ,Tm+k ) be a sequence of m + k + 1knots.
