Tecplot 360 is a software package used in post-processing numerical simulation results.
(source: https://en.wikipedia.org/wiki/tecplot )
tecplot 360 is a computational fluid dynamics (cfd) and numerical simulation software package used in postprocessing simulation results. tecplot 360 is also used in chemistry applications to visualize molecule structure by postprocessing charge density data.[4]
common tasks associated with postprocessing analysis of flow solver (e.g. fluent, openfoam) data include calculating grid quantities (e.g. aspect ratios, skewness, orthogonality and stretch factors), normalizing data; deriving flow field functions like pressure coefficient or vorticity magnitude, verifying solution convergence, estimating the order of accuracy of solutions, interactively exploring data through cut planes (a slice through a region), isosurfaces (3d maps of concentrations), particle paths (dropping an object in the "fluid" and watching where it goes).
