Adaptive solver: operating mode in 3D

An example in magnetostatic 3D

You can use this new functionality with a 3D magnetostatic example, available from the supervisor. In the Open example context:

Technical tutorials > Magneto Static application contactor > Static study > Physics

Step Description Illustration

For this example, you can start from the mesh carried out by the aided mesh.

By definition, this mesh is « non-adapted » to the physics of the problem.


To observe the local impact of the adaptive solving, start from an aided loose mesh such as:

  • Deviation = 0.1 (Relative)
  • Coefficient of relaxation of the line type = 0.9 (User)
  • Coefficient of relaxation of the face type= 0.9 (User)
  • Coefficient of relaxation of the volume type= 0.75 (High)

3 Modify the angle of the blade around Y-Axis:

[ALPHA] = -8°

4 To activate the adaptive solver, the user must select Adaptive solver in the scenario that he has created.
5 The user solves this scenario by opening the dialog box Solve, which exists in the Solving menu and by selecting Solve solving scenario

Modify the Adaptive solver options:

Solving > Adaptive solver options > Edit


User threshold (0.0 < s <= 1): 0.1

Maximum number of iterations: 4

Volume regions to be excluded: none.
