Post processing

from Wikipedia, the free encyclopedia

The term postprocessing describes the post-processing and preparation of results of a computer simulation , such as a numerical flow simulation . One tries to convert the resulting large amounts of data into an understandable form of presentation, e.g. B. in graphics and animations .

Postprocessing is often done with a separate program that has special functions and methods for visualization . Examples are TecPlot or the open source project OpenDX .

The term is also used for precise position determination with differential GPS (two or more satellite receivers). Here it describes the subsequent, more precise evaluation of the distance or phase measurements with final orbit data , while the online location determination only has preliminary data available. The evaluation of quasi-difference measurements (distance or time measurements disturbed by external circumstances) can also be done better off-line, for example by introducing nodes to stiffen the geometry.
