+# reset imt values of truncated mesh
+
+Source imt values are the truncated imt values minus the node values that need to be reset.
+
+This example removes materials greater than MAX_MAT.
+The removal can leave behind node values that need to be reset.
+We do not want to remove the nodes as we want to keep these cells.
+
+Main command file with the truncation calls:
+
+```
+
+# truncate top of mesh, remove materials gt 8
+
+define CMO cmotet
+define MAX_MAT 8
+
+eltset/edel/ itetclr / gt MAX_MAT 
+rmpoint element eltset,get,edel
+rmpoint/compress
+resetpts/itp
+
+# FIX imt of nodes left behind after removal of cells
+
+infile reset_truncated_nodes_imt.mlgi
+
+```
+
+Macro File reset_truncated_nodes_imt.mlgi:
+
+```
+# macro to fix node imt values left over from truncation
+# must define CMO when calling this macro
+# must define MAX_MAT
+
+# create set of points with good values
+# fix using nearest interpolation from good set
