You&#8217;ll explore the governing fluid flow equations\u2014the Navier-Stokes equations\u2014and learn how to discretize and solve them using finite-difference and finite-volume methods.<\/p>\n\n\n\n<p>In addition to the fundamental concepts mentioned above, this CFD training covers grid generation, boundary conditions, and solution algorithms, preparing you to solve complex flow problems confidently.<\/p>\n\n\n\n<p>The focus is on presenting fundamental ideas and some of the most widely used methods while pointing toward possible extensions. Key concepts covered include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Deriving approximations for derivatives using Taylor series expansion and polynomial fitting<\/li>\n\n\n\n<li>Determining the order of approximations, both analytically and through specially designed numerical experiments<\/li>\n\n\n\n<li>Approximating surface, volume, and time integrals<\/li>\n\n\n\n<li>Interpolating variables on computational grids<\/li>\n<\/ul>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Advanced numerical techniques<\/h3>\n\n\n\n<p>A major strength of the series is its comprehensive coverage of advanced numerical techniques. You&#8217;ll learn about iterative solution methods for linear algebraic equation systems, essential for efficiently solving discretized equations. Techniques covered include conjugate gradient methods for solving large linear systems, multigrid acceleration for speeding up convergence and preconditioning for modifying the linear system.<\/p>\n\n\n\n<p>The curriculum extensively explores higher-order discretization methods up to 4th-order accuracy for both finite-difference and finite-volume approaches. Foundational algorithms, such as <a href=\"https:\/\/blogs.sw.siemens.com\/simcenter\/cfd-speedup-with-simplec\/\" target=\"_blank\" rel=\"noreferrer noopener\">SIMPLE and related methods<\/a> for computing incompressible flows, are also examined.
