zone.field.tol

Syntax

f := zone.field.tol

zone.field.tol = f

Get/set the tolerance used for the polynomial method of extrapolation. The default is 1e-7.

This value is used to detect a degeneracy in the matrix used to solve for polynomial extrapolation coefficients. If a degeneracy is detected, the matrix is revised to assume there is no change in that degree-of-freedom.

Returns:f - the tolerance used for polynomial method of extrapolation Accepts:f - the tolerance used for polynomial method of extrapolation
