4.5 CONDL1

Aim:

Construct a D.S. NDL1 from a D.S. MAIL. The algorithms described in this guide call function NDL, which assigns the number of the last degree of freedom associated with node I to NDL(I+1) (using the convention NDL(1)=0). to initialize this function, the module calls function LRNDL1, and then:

• if the number of degrees of freedom at each node ND is constant, NDL(I+1) = I * ND
• if not, NDL(I+1) = the number of the last degree of freedom associated with node I, and is read into NDL1.
