This command test a mesh for valid jtet connectivity.  If the mesh is a network it allows for jtet loops; in this case the jtet relationship is not reflexive but, for example if the loop has length 3.

Normally degenerate faces may not have neighbors with a different number of nodes; however, if  a scalar mesh attribute 'jtet_reduce_nnd' is defined and has the value 1, faces will match if the node numbers are the same even if a node number appears more that once.

elmtest /[/nwrite] where nwrite is the number of warning messages to print.  The default for nwrite is 20.
