1) The ideal left ventricle is modelled as a semi-long-axis ellipse and I use gmsh to get the mesh of the ideal model. 2) I have a model of the real left ventricle, if I transform the surface point coordinates of the real model into a cylindrical coordinate system and then use the cylindrical coordinate system to move the ideal mesh
I would like to enquire about the feasibility of this

As I already said, there is a function in deal.II that *does* the transformation, but you have to tell it *what the transformation is*. It is not enough to just provide two geometries, you actually have to provide the transformation from one to the other.
