Hi
Eugene Mamulova
Discovery Explore uses
voxel-based approach that eliminates the need for time-consuming mesh generation and so you can't display mesh. You can use the Fidelity bar under the simulation icon in Explore to increase or decrease the fidelity similarly to what we do to make mesh courser or finer. You can use Size Preview option to display the size of element being used.
Although you can view mesh in Discovery Refine mode from Show Mesh button in the Result Arc.

Regards.
