METAPLANE

(optional) define a cutting plane for MESHFREE points

Points outside the METAPLANE will be cut off. The METAPLANE flag takes a number as parameter. METAPLANEs are grouped together according to this index, allowing for more complex deletion logic: If there are multiple METAPLANE groups, points are only deleted if they are considered outside with respect to all groups. Within each group, points are considered outside if they are outside any of the METAPLANEs of this group. The number has to be >=1. Example:
begin_alias{} "plane" = " BC$...$ ACTIVE$...$ IDENT%...% MAT$...$ TOUCH%...% MOVE$...$ LAYER0 CHAMBER1 METAPLANE1 " end_alias
