TALK=T;RUN(1,1) DISPLAY PLANT is used for specifying two time-step sizes. The first is set equal to 5 sec. The second time step is computed by dividing the smallest cell size by the largest velocity. The solved-for variable is H1; but, since the actual solution is of not of interest, no initial or boundary conditions are introduced. The non-uniform grid and velocity field are initialised for expected size of the second time step to be 0.1 sec. PLANT information : * Data input groups used: 2, 19 * Ground groups planted : 1, 2, 19-3 * Headings used : SCTS?? * Functions used : SUM * Commands used : IF, REGION, TEXT. ENDDIS PLANTBEGIN <<<<<<<<<<<<<<<<<<<<<<< Comment ends <<<<<<<<<<<<<<<<<<<<< ** Ask PLANT to introduce first time step, 5 seconds.DT=5. REGION(1,1,1,1,1,1,1,1) REGION command is used to control this simple setting. Its first six arguments limit DO loop to perform single action over first time step defined by the last argument pair. <<<<<<<<<<<<<<<<<<<<<<< Comment ends <<<<<<<<<<<<<<<<<<<<< ** Choose the smallest cell size at the start of each iz-slab for the last sweep of the first time step. RG(1)=GREAT DXG2D - cell size in X-direction, DYG2D - cell size in Y-direction, DZWNZ - cell size in Z-direction, RG(1)=AMIN1(RG(1),DXG2D,DYG2D,DZWNZ) IF(ISTEP.EQ.1.AND.ISWEEP.EQ.LSWEEP) Command IF restricts the whole-domain-default extents of PLANT statement. The arguments of IF command instruct PLANT to introduce the logical conditions of the bracketed expression. The execution of the statement returns the auxilliary variable, RG(1), with the smallest cell size over the whole domain. <<<<<<<<<<<<<<<<<<<<<<< Comment ends <<<<<<<<<<<<<<<<<<<<< ** Output of smallest cell size using summation in one cell at 1st time step, last sweep for checking. SIZMIN=SUM(RG(1)) TEXT(Smallest cell size) REGION(1,1,1,1,1,1,1,1) /ISWEEP.EQ.LSWEEP The function SUM is used in above three lines just to dump into globcalc file the value of RG(1) headed by the character arguments of TEXT command. <<<<<<<<<<<<<<<<<<<<<<< Comment ends <<<<<<<<<<<<<<<<<<<<< ** Choose the largest velocity value just before the second time step calculation RG(2)=AMAX1(RG(2),U1,V1,W1) IF(ISTEP.EQ.2) ** Output the largest velocity using summation in one cell at 2nd time step for checking. VELMAX=SUM(RG(2)) TEXT(Largest velocity) REGION(1,1,1,1,1,1,2,2) Auxiliary variable, RG(2), will be the largest velocity value as result of the above statements at the second time moment. It will be dumped in globcalc file and appropriately headed. <<<<<<<<<<<<<<<<<<<<<<< Comment ends <<<<<<<<<<<<<<<<<<<<< DT=SIZMIN/VELMAX REGION(1,1,1,1,1,1,2,2) The final stage of time step settings: second time step size, DT, is set as division of smallest size by largest velocity. <<<<<<<<<<<<<<<<<<<<<<< Comment ends <<<<<<<<<<<<<<<<<<<<< PLANTEND infrbegin debug f tgrid f formula f infrend ************************************************************ Group 1.
