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 […]

Variable names different than those in Fluent.

Problem: I loaded some data into Tecplot from Fluent and the variable list came out different than I expected in Tecplot. Some of the variable names have t-1 or t-2 after them. Some of them have #1 or #2 or #3 after them. What is Tecplot doing with the names of the variables? Solution: Fluent allows for different variables in one zone than in another while Tecplot requires that all […]
