The position of the first rolling element for rolling element bearings can be defined globally using this settings. See Position of first rolling element.

In case of bearings with clearance and very small loads it might happen, that only one rolling element is loaded. This can lead to convergence problem as there is zero stiffness normal to the loading. Then setting the option to "Load direction between rolling elements" might be helpful. Else the setting "First rolling element on load direction" leads to the maximum contact stress and the minimum bearing life in most cases. Usually there is only a noticeable effect on bearing with a low number of rolling elements.
