All of these routines also have in their argument list four auxiliary storage unit numbers, NTAPE1, NTAPE2, NTAPE3, and NTAPE4. The latter three units are available for use by the analyst if they are assigned positive unit numbers. The value of NTAPEI (when > 0) represents the auxiliary unit on which data generated by ELPOST are to be stored. g. rate of heat generation) that varies over the element. in the present program the calculation of the element column matrix is carried out in subroutine ELCOL.

Several specific examples of typical property data will be given in the example applications beginning in Chapter 10. Consider a typical nodal point in the system and recall that there are NG parameters associated with each node. Thus at a typical node there will be NG local degree of freedom numbers (1 J NG) and a corresponding set of system degree of freedom numbers. If! denotes the system node number of the point, then the NG corresponding system degree of freedom numbers are calculated by utilizing Eqn.

However, they vary greatly from one program to the next. For example, large commercial packages such as PAFEC [39], tend to have special control macros, free-format input, and extensive graphics to simplify the ease of use. Other small systems may use special macros to simplify the order of data input. An example of this type of code is the one presented by Taylor [69] in the appendix of the text by Zienkiewicz. Other programs often use the more classical type of fixed format data input. That is the procedure utilized here in the MODEL program.
