The errors, especially for the second derivative are
one order higher especially around values +- 2,4,8,16,32,64.
Setting the tolerance for second order derivative just
above the maximum error I got for -63.99999303065484 which,
is 0.00014201125474823262.

Calculate Biot coefficient, such that solid compressibility stays the
same as before. Now alpha = 1 - K_S/K_SR.
