This function should be used with $xd. 
 21 is the gate contact. It comes with the setting of Schottky barrier setting [[$Schottky]] and gate bias setting [[$gatebias]]. If the electron affinity is used, user will need to setup [[$gatewithworkfunc]] instead of using [[$Schottky]]
 3 is for the source contact. The program will find the barrier of contact with the doping setting. 
 4 is for the drain contact. The program will find the barrier of contact with the doping setting. 
 7 is no contact. Actually this is redundent. But some time it goes with some advance settings.
 9x is for thermal contact. 98 is fixed boundary setting. Where the contact area is set as constant temperature. 99 is for thermal diffusive boundary condition.
