Slot Type 61 can be used only as slot for the inner rotor of a Wound Rotor Synchronous Machine (WRSM).
To set up a slot type 61 you need to replace the rotor slot geometry bloc in your machine file by this code and edit it with your values :
Input.Geometry.type_slot_shaper = 61;
Input.Geometry.H0r = 1e-3; %[m]
Input.Geometry.H1r = 1.5e-3; %[m]
Input.Geometry.H2r = 30e-3; %[m]
Input.Geometry.W0r = 12e-3; %[m]
Input.Geometry.W1r = 14e-3; %[m]
Input.Geometry.W2r = 12e-3; %[m]
