TALK=T;RUN(1,1) display Q1 for illustrating the influences of various factors when the default selref=T is selected. The process is transient. A single cell has a uniform source of C1. Heavy linear under-relaxation is used so as to necessitate many sweeps for convergence. Neither the solution nor the number of sweeps is influenced by XULAST, YVLAST, ZWLAST, TLAST OR RHO1. Both are influenced by: RESFAC, FIINIT(C1) and the relaxation factor. enddis ************************************************************ Group 1.
