                         double tol)

Tests a material by comparing the computed derivatives with the numeric derivative of the same. Different materials are specified for testing dFdl and dFdldot in case different parameter settings are needed to numerically compute the different derivates.

Parameters:

mat - material to test for dFdl

matdot - material to test for dFdldot

tol - tolerance by which the computed and numeric derivatives should match. Typically, this should be around 1e-8.

testMaterial

public void testMaterial(AxialMaterial mat,
                         double l,
                         double ldot,

                         double ex,
                         double tol)

Tests a material by comparing the computed derivatives with the numeric derivative of the same.

Parameters:

mat - material to test

tol - tolerance by which the computed and numeric derivatives should match. Typically, this should be around 1e-8.
