Channel sphere 3D remeshing
Author: Vicente Mataix Ferrándiz
Kratos version: 7.1
Source files: Channel sphere 3D
Case Specification
In this test case,
The following applications of Kratos are used:
- FluidDynamicsApplication with the MMG module
- MeshingApplication with the MMG module
Adaptative remeshing of 3D fluid channel with sphere using Hessian of velocity as metric measure. It consists in a channel 3x1x1, a sphere of 0.5 diameter and with a velocity of 1 m/s in the inlet an zero pressure in the outlet. The total time of simulation is 1.2s with a time step of 0.01s. The remeshing is performed each 20 steps.
The mesh corresponding before remeshing corresponds with:
Results
The results obtained corresponds with the following:
