vResolution boxes

[knuwater109-spec]

Hello,

I am trying to use variable resolution in DesignSPHysics (FreeCAD GUI).

Right now, I created a solid cube inside vresolution_boxes, and I thought that placing the cube there would automatically apply variable resolution. However, when I run the case, it does not seem to work.

So I would like to ask:

Is simply creating a solid cube inside vresolution_boxes enough to apply variable resolution?

If not, what is the correct procedure to make variable resolution work?

Do I need to assign additional properties or parameters to the box besides putting it inside vresolution_boxes?

Is there any example project or sample case showing how to set this up correctly in the FreeCAD GUI?

I would appreciate any guidance.

Thank you.
