From mesh control, you can do inflation by selecting the body surface as boundary

Hi Ibrahim,

You can reduce the mesh count near the surface without effecting the far field mesh, by controlling the growth rate. By default, growth rate would be 1.2, using growth rate along with boundary layer would the best option.

Hope this help you.

Thanks & Regards,

Rajesh.

Hide the body. Inflate fluid around the body selecting surfaces of fluid in contact with body. put 7 to 12 layers, choose option of first layer depth and define (forexample 0,02 mm).

Good luck
