|  Specifies the VSS sparse direct solver matrix reordering method: 
				    
				  HEAT - Used for one degree of freedom per node models such as in heat transfer solutions. 
					  SHELL - Used for six degree of freedom per node models such as in structural models with shell and line element types. 
					  SOLID - Used for three degree of freedom per node models such as in structural models with only solid elements. 
					 SOLVER - Directs the solver to determine the best reordering method based on the input stiffness matrix. 
					  AUTO - The program picks the best method based on the element types and solution selected in the model. 
					 
  Additional reordering options can be selected using the 
					 RESEQGRIDMETHOD directive.
