We present an approach to the extraction of FTLE ridges for 2D unsteady vector fields under long integration times.

Secondly, FTLE can produce false positives, i.e. ridge lines due to high sheer instead of flow separation. We consider the particular approach [WRT18] .

Sep 26, 2024 · We present a new method for extracting FTLE ridges for series of integration times which is able to show how coherent regions and their borders evolve over ...

With longer integration time, the FTLE ridges become sharper, i.e. LCS resolve into clearly defined thin lines. ... longer integration time, the FTLE ridges ...

The underlying particle system allows for efficient sampling of ridges for a sequence of multiple integration times. Visualizing how FTLE ridges emerge over ...

FTLE ridges can move towards each other and can in fact come very close to each other with increasing integration time. A good FTLE method should be able to ...
