1. Improvements of the Interpolation and Non-Orthogonal Correction Schemes in Caelus Dr. Chris Sideroff Dr. Darrin Stephens
2. Mesh Quality Issues • Sensitivity to mesh quality widely reported • Two main metrics used to quantify “quality” • Non-orthogonality • Skewness • Non-orthogonality tends affect gradient reconstruction, i.e. diffusion terms • Skewness tends to affect face interpolation, i.e. convective terms
3. Central Interpolation • Central-based schemes (linear, limitedLinear) are one dimensional – very susceptible to skewness d
4. Upwind Interpolation • Include gradient to get better than 1st order accuracy
