Notification for low bottom clearance

The default value for minimum tip clearance c_min relative to m_n is 0.13. It can be set from 0.001 to 0.99. If the tip clearance factor c* is specified in the geometry data, it is only used if it is less than the maximum tip clearance c_max relative to m_n (default value = 0.75). c_max can vary between 0.00001 and 1.0.

A notification for low tip clearance is issued if the actual tip clearance relative to m_n is less than 0.2. The value can vary between 0.05 and 0.5.
