Small Feature Meshing Flag
By enabling the Small feature meshing flag, you can set the type and tolerance for meshing of small features in the model.
Based on the value of tolerance specified, the small features are detected in the model and are meshed separately to create a better quality mesh. Three different small feature meshing types are available. An Absolute value or Relative value of tolerance can be specified. The third option is to set the tolerance as a factor of mesh size and is called the Mesh Size Factor. For example, with the mesh size factor set, a tolerance of 0.5 will detect anything less than mesh size x 0.5 as an small feature.
