FDK in knee joint


We have constructed a new knee joint in lower limb model based on FDK method. We find the FDK model can output the COP (the center of pressure) information, but the COP is in global coordinates frame. How can i output the COP in local coordinates frame of tibia?
Many thanks !

Best whishes!


Dear Chen,

It will be better if you can see the description of AnyRefFrame class.

You can find the following equation there:
GlobalVector = LocalVector * Axes’;

LocalVector = GlobalVector * Axes;

I hope this may help you.

Best regards,
