HOMARD : Le front |
![]() |
This test-case simulates the transportation of a pollutant in a water flow.
The flow between the lower left structure rises to bypass the obstacle,
and exits from the lower right corner.
It is well known that the major difficulty is with the accuracy of the
calculation around the pollutant. Thanks to the mesh adaptation with HOMARD,
at each time, mesh is the best in these zones.
It can be seen that the mesh is refined upstream the pollutant.
It remains fine at the center of the high concentration zone to improve
calculation accuracy in this area. Lastly, it is unrefined at the rear
of the front, when the pollutant has gone away.
Successives meshings are presented here. The number in the corner represents the number of adaptations iterations.
