+
+Sets point types and material regions by calling** surfset **and** regset**
+routines.** **Generate constraint table. The material (imt1) attribute is set
+based on the **mregion** commands. Interior and external boundary nodes should
+be assigned to exactly one **mregion**; these nodes will be assigned an
+**imt1** value that corresponds to the **mregion.** A node which is on an
+interface will be assigned to any** mregion **and will be given an **imt1**
+value of "**interface**" (an integer equal to one more than the number of
+material regions.) Node types are assigned based on whether a node is on a
+surface and what type the surface(s) is.
+
+This command must be executed before **connect.** FORMAT: **setpts**
+
+**setpts/no_interface**   
+This allows one to set the imt values of nodes without getting any nodes
+labeled imt=interface. This is useful if you do not want settets to create
+parent child chains at interface points. The actual imt value given may be
+determined by roundoff error so should not be used in cases where there are a
+large number of interface points.&nbsp_place_holder; It is useful for setting
+imt values of an rzbrick mesh in which interface points only occur due to the
+coincidental point very near the geometry defining surface.
+
+**setpts**/**closed_surfaces**/**reflect**   
+The **closed_surfaces** option works with geometries in which all regions and
+mregions are defined by closed surfaces. The nodes that fall on more than one
+surface are labeled as interface nodes. Nodes which fall on exactly one
+surface are labeled external reflective boundary nodes. Nodes which are
+external boundary interface nodes are not labeled correctly and
+**resetpts/itp** must be called to correct the point types. An input file
+using the closed_surfaces option might look like: cmo/create/s1///tri
