How to check the stability analysis of complex opamp circuit in Ltspice

[hiyo]

I am attaching the simulation file of one of my circuit.It consists of many opamps and BJT's. I don't know how to check the stability of this circuit(I know it for single opamp circuits).

My input is V3(I_PT100_SET) and output is I_PT100_ACT .
I can see some ringing initially at output .

Can you please help me to check the stability and to compensate it.

You might have to include some of the "AD" models for that.

Add " .options cshunt=1f " to your schematic. Shortcut is the s key. The sim ran for me after doing this.
