MESHFREE goes through all existing boundary elements whose alias is one of FirstAliasOfGeometryTheNodesAreTakenFrom,
SecondAliasOfGeometryTheNodesAreTakenFrom, ...
From their nodes, new elements of BND_point are created which take the alias AliasTheNewPointsAreSupposedToTake.
The aliases have to exist, i.e.
begin_alias{}
...
"AliasTheNewPointsAreSupposedToTake" = " ... " # alias for new points
"FirstAliasOfGeometryTheNodesAreTakenFrom" = " ... " # first original alias
"SecondAliasOfGeometryTheNodesAreTakenFrom" = " ... " # second original alias
...
