! For the case where either RdtnMod=0 and ExtcnMod=0 and hence %SS_Rdtn data or %SS_Exctn data is not valid then we do not have states, so simply return
! The key here is to never allocate the dXdu and related state Jacobian arrays because then the glue-code will behave properly

if ( p%totalStates == 0 ) return
