Above is an example of viflow7 input file

line 1 :

itit : problem title

line 2 consists of (in order) :

xbeg : x coordinate at beginning of flow path

ybeg : y coordinate at beginning of flow path

vinit : initial velocity of the flow

nseg : number of segments representing slope (20 max)

line 3 consists of (in order) :

ffric : hydrodynamic friction factor-use 0 at present

gfac : acc. of gravity - use 9.81

delt : time increment

iter : max. no of iterations in heun procedure

line 4 consists of (in order), plus (1 line for each segment up to nseg) :

x : x coordinate at end of segment

y : y coordinate at end of segment

th : thickness of flow

dens : unit weight of flow

visc : viscosity of flow

yld : yield resistance of flow

last line:

**** : four stars indicate input termination
