WebA high-order mesh connects grid points with a non-linear polynomial function (e.g. second degree quadratic), thus the technique is called “mesh curving.”. CFD meshing software that uses mesh curving or high-order mesh generation can typically use degree 2 (quadratic) to degree 4 (quartic) polynomials. If the technique were applied with a ... WebAbstract Mesh refinement is an important tool for editing finite element meshes in order to increase the accuracy of the solution. Refinement is performed in an iterative procedure in which a solution is found, error estimates are calculated, and elements in regions of high error are refined.
