ANSYS Forte settings issue

[Hasan]

New to this and learning reduced errors but still have this problem while setting valve inputs. A spark ingnition two valve enigne. Probably other errors too, there is a gap in the CAD model between the valve seat and the valve face of 0.5 mm. In the inputs I    Exceeded limit of 500 iterations, please check boundary condition settings.
Ignoring update of min_lift because it is currently a Workbench parameter.
It must only be updated from Workbench.

More errors to solve, thanks in advance for any helpers outthere.

Everytime I enter seat_exhaust and Exhaust_valve_near_seat_surface in the bottom left seletion, the latter disappears once I select Apply and then save, as shown above.

Image below is a sectional mesh view, showning one valve while the other is hidden, the inlet valve on the left. The gap between the valve edge face and the valve seat surface is 0.5 mm.
