Use the Scheme commands below to ignore the secondary gradient of Heat Flux. It is effective in improving convergence of the energy equation in cases with high skewness of the mesh. For the entire region: (rpsetvar ‘temperature/secondary-gradient? #f) Only for the Wall: /solve/set/expert/use-alternate-formulation-for-wall-temperature? Yes Only for Shell Conduction: (rpsetvar ‘temperature/shell-secondary-gradient? #f) Note the parentheses are required for the input.
