`block.field.tol`

Syntax

- f = block.field.tol()
- block.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 - tolerance used for polynomial method of extrapolation

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