Tecplot 360 2011
CFD Analyser
CFD Analysis Tools
CFD Analyser has been rolled into Tecplot 360 and is no longer a seperate product. Save time finding, extracting and processing the critical information in results with the CFD analysis options. Analyse tools help users examine grid quality, perform spatial integrations, generate particle trajectories, extract flow features, and estimate numerical errors.
- Calculate grid quantities such as aspect ratios, skewness, orthogonality, and stretch factors.
- Calculate pressure coefficient, vorticity magnitude, and other flow field functions.
- Detect and extract shock surfaces, vortex cores, as well as seperation and reattachment lines.
- Integrate mass and momentum flow rates to verify convergence.
- Integrate particle paths in time and space. Particles may be massless, or you can give them mass and size and let drag, gravity, and buoyancy influence their trajectories.
- Estimate the order of accuracy of your numerical solutions with Richardson extrapolation analysis.
When you’re analysing CFD data with Tecplot, CFD Analyser saves you time finding, extracting and processing the critical information. CFD Analyser provides many of the functions commonly used to calculate variables and perform integrations. Count on CFD Analyser to quickly get the most out of your data.
The function set is an enhanced version of the classic NASA PLOT3D Calculator concept. CFD Analyser helps you examine grid quality, perform spatial integrations, generate particle trajectories, extract flow features, and estimate numerical errors.
CFD Analyser loads automatically at run time, becoming part of Tecplot's Tools menu. When selected, CFD Analyser has its own set of dialogs, facilitating the use of its extensive analysis capabilities. Custom macro commands are also included, allowing features to be automated.
