Easiest Way to Increase Initial Cell Voltage of model

I am using the application library 1D battery model and have changed the cathode to LFP and the anode to graphite. The initial cell voltage is at 3.3V and i need a start voltage of 3.68V how do i change the comsol model to show this voltage? I am fine with the OCV SOC curve i just want the initial voltage to be higher. I have tried increasing the anode species concentration and it has increased the voltage to 3.4V but i still need it to be higher

Figured out it was my C rate was too high even after increasing concentration in anode and decreasing concentration in cathode to get 100% SOC
