Ah, apologies, the default op-amp for the simulator put in TL082, I didn't mean to imply that was my final selection. I didn't realize op amps came with short circuit protection, I'll be sure to get a single-sided one with that functionality built in.
Could you elaborate on what you mean by "non-linear Force/Voltage output?". I was under the impression that so long as I kept the current draw well below the limits of the supply chip I could expect idealistic behavior from the circuit (results would be far more dependent on the individual variation in the resistors used than to imperfections in the power supply). I was envisioning using a L7805CV to supply the 5V and a LM317 for the 2.5V
