NettetThe linear upwind scheme (and all NVT/TVD schemes) use the gradient of the field in question to calculate the final divergence value. That last entry is you telling linearUpwind how you want the gradient calculated. In this case 'grad(U)' means 'Calculate this however you're calculating grad(U) in the gradSchemes setting.' Nettet4.5 Numerical schemes. The fvSchemes dictionary in the system directory sets the numerical schemes for terms, such as derivatives in equations, that are calculated during a simulation. This section describes how to specify the schemes in the fvSchemes dictionary. The terms that must typically be assigned a numerical scheme in fvSchemes range ...
