Hi,

Rephrasing the title, shall I see Cell.velGrad as a gradient with respect to classical spatial coordinates (Eulerian), or a gradient with respect to Lagrangian coordinates ?
Taking a wild bet, I would say Eulerian (outside Body.id, we do not have much of Lagrangian stuff, do we ?) but could you please confirm ?
