From what I can see, each of the three diode strings is driven by a single current regulator. Maybe you could you describe your concerns using component reference designators?

You have three groups of circuits, but I'll refer to one group.
The opamp and mosfet forms a basic Volt to current converter and its controlling current thru the diodes.
The LM317 is also configured as a current regulator and it also (trying) control current thru the diodes.
That's what I think is causing the simulation convergence problems.
