What method of integration does Tecplot 360′s Analyze menu use?
Hey every one,
I'm calculating average quantities over a domaine using "integration method" via Analyze menu. I would like to know how to get the equation that Tecplot uses to do this calculation (integrationn)?!:confused::confused: Thanks for your help Souria, |
This paragraph on page 304 of the Tecplot 360 User manual located at this link: http://download.tecplot.com/360/current/360_users_manual.pdfstates:
Integrations of a variable or variable function use the trapezoidal method, and are second-order accurate. For each segment, face, or volume cell, the appropriate nodal or cell-centered values are averaged and multiplied by the cell length, area or volume. The calculation sums the resulting qualities over the zone or specified subset to product the integrated result. Standard deviation is calculated using the sample standard deviation method (the values are taken to be a sample of a population, and the sum of the squares of the value is divided by N-1 rather than by N). A review the chapter CFD Data Analysis in the same manual should be helpful if you require more information. Regards, Scott |
Results of your integration
Hi Souria,
I am interested in the results of your integration. Were the results you were getting from Tecplot consistent with your expectations? Can you tell me a little bit more about what you were trying to do. I ask because we strive to make Tecplot as accurate as possible and I want to make sure you are getting the right results.

Hey Durell4,
My aim objective is to see the evolution of flow quantities (velocity, vorticity...) over time. So, with this integration shows sharp periodicities of the flow dynamics thus yes, the results are in confirm with i am expecting to find. I don't know if i respond to your interrogations, I can give more details if you want. But, I didn't find answer to my question, I'm searching the formulation/equation that Tecplot uses for the integration :confused::confused: ??!! @ Scott-rumage : Your link doesn't work !!! Thanks |
Here is a link to the manual: http://download.tecplot.com/360/curr...ers_manual.pdf
and, as a reference, here is link to Tecplot's documentation page: http://www.tecplot.com/support/documentation/ Thanks, Scott |
