The nodes on the top and bottom layers of the piezoelectric material are then coupled for voltages. This essentially creates a common node for each surface that can be used to create an electrode connection, and an external load resistor can be added in between these coupled nodes. The resistor is added by creating a single two-node CIRCU94 element between these coupled nodes, and the value of the resistance is defined as a real constant.
Dear Raja
Actually its easy u need just add a new two nodesand couple the upper and lower piezoelectric electrodes with those new nodes , then assign a new element type with the value of the resistor as follow
R1 is the resistor value
ET,3,CIRCU94,0 ! Set up the resistor
R,1,R1
TYPE,3
E,first_new_node,second_new_node
