	To preselect nodes for the 'C' option, include one or mode <tt>Select</tt> commands in the [[FEA Input Files#Header\|header]] using its <tt>node</tt> attribute to specify the node by number.

A better way to select nodes in <tt>XML</tt> files is to select them using a [[FEA Boundary Conditions#Selecting Nodes\|<tt>select='1'</tt> attribute]] on [[FEA Boundary Conditions#XML Input Files\|BCLine or BCPt Commands]] used for create [[FEA Boundary Conditions\|boundary conditions]].
