Inductor simulation using 3D model to get inductance and saturation chara

I have a copper bar in between cores in model ( its a planar ind),want to calculate inductance of this at different frequencies. Can anyone help me with general workflow or steps for inductance simulation. Already assigned materials for components in 3D model. The core has non linear characteristic in BH curve. I want to know how to calculate inductance of this and what are general steps to be followed.
