In mode #4 WERAMI computes properties along an arbitrary X-Y path through
a two dimensional section. The path coordinates are read from a file and
may be specified as a list of X-Y points (one pair per line), or as a
polynomial U(V). The file format for the path data with the latter
option are:
LINE 1: VMIN VMAX IXY
LINE 2: UMIN UMAX DU C0 C1 C2 C3
LINE 3-N: To specify multiple paths, LINE 2 may be repreated as
many times as desired.
Where
IXY - determines the association of the polynomial variables
(U,V) with the sectioning variables (X,Y), if IXY = 0,
then U->X and V->Y, otherwise U->Y, V->X.
VMIN,VMAX - the range of V over which the polynomial is valid, if
a computed value of V exceeds these limits (or the that
of the corresponding X-Y variable), WERAMI assumes
that it has reached the end of the path. To assure that
WERAMI calculates the path over the entire range of X-Y
conditions, specify values for VMIN and VMAX that are
beyond the limits of the corresponding X-Y section
variable.
UMIN,UMAX,DU - UMIN and UMAX are the minimum and maximum values of U along
the path and DU is its increment. If DU > 0, the path is
calculated from UMIN to UMAX, otherwise the path is
calculated from UMAX to UMIN. If a value of U exceeds the
limit WERAMI assumes that it has reached the end of the path.
To assure that WERAMI calculates the path over the entire
range of X-Y conditions, specify values for VMIN and VMAX
that are beyond the limits of the corresponding X-Y section
variable.
C0,C1,C2,C3 - are the coefficients in the polynomial:
U = C0 + C1*V + C2*V**2 + C3*V**4
