Accuracy analysis of gradient reconstruction on isotropic unstructured meshes and its effects on inviscid flow simulation
Abstract The accuracy of gradient reconstruction methods on unstructured meshes is analyzed both mathematically and numerically. Mathematical derivations reveal that, for gradient reconstruction based on the Green-Gauss theorem (the GG methods), if the summation of first-and-lower-order terms does n...
