How does Tecplot calculate cell or face-centered quantities?

Question: How does Tecplot calculate cell or face-centered quantities? Answer: Tecplot uses simple arithmetic averaging to calculate cell- (face-) centered quantities. Integrations are done using the trapezoidal method, which is second-order accurate. For each cell, the cell-centered value of the quantity being integrated (integrand) is multiplied by the volume of the cell, and the result is summed over all cells. If the integrand is node-centered, the cell-centered average is calculated […]
