How does Tecplot calculate cell or face-centered quantities?

Calculation, Data Format, Tecplot 360 May 6, 2011

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 […]

Line breaks in the line legend

Tecplot 360, Text, XY Plot April 20, 2011

Problem: How can I add line breaks into the line legend labels? Solution: If you define the line mapping name as the variable or zone name, add \n to the variable or zone name (defined in Data > Data Set Info) at the desired location of the line break.  If you are using a static Map Name defined directly in the Mapping Style dialog, add \\n  at the desired location of the line […]

Variable names different than those in Fluent.

Fluent, Tecplot 360 June 3, 2010

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 […]

Assigning different colors to zones

Contours, Tecplot 360 May 28, 2010

Problem: Tecplot 360 2006 Tecplot Focus 2006 and earlier versions of Tecplot products assigned different colors to zones whereas Tecplot 360 2008 Tecplot Focus 2008 and later products assign black to all zones by default. Is there a way to change this default to make the Tecplot 360 and Tecplot Focus 2008 versions behave like the 2006 and earlier versions? Solution: Yes. Please check your tecplot.cfg file in your Tecplot […]
