Mesh simplification except details

[Jakub Curylo]

Hi,

I need to prepare mesh 3D of car seat to further dynamic analysis. Because the mesh has high resolution it is necessity to make a simplification using one of the available options in MeshLab. What module I have to use to get the mesh with lower resolution in places where the faces are simple but higher resolution where details must be preserved. The screen of the object I attach to this message.

Thank you for any advice in advance.
