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
