Martin Diehl 021d614daf using Voigt notation
This is a bugfix with a change of behavior
2021-11-19 20:44:30 +01:00
Martin Diehl ff9fa1d4f7 using Voigt notation instead of proprietary scaled 6x6 notation
Note: This results in a change of behavior for the transformation
systems of dislotwin. I assume that this fixes a bug, but still need to
confirm where the equations in lattice_C66_trans come from

Martin Diehl f5fe0b9dca bugfix: change of behavior
negative values for the resolved stress do not make sense.
The paper does not take this into account (eq (14), Cereceda et. al
2016). According to my understanding, only the non-thermal contributions should be
substracted, so abs(tau_pos)/abs(tau_neg) would not be sufficient.

Sharan Roongta bd9cae11a5 allow multi line scalar list items.
If a scalar list item has ',', the parser would consider it as a separator and not a part of the string
For the moment, this scalar item is enclosed with double quotes ""
In the next step, the flow parser should be able to use this quotes as an indicator for strings

Martin Diehl 85735605f8 more flexibility for the L in the load case
Note that mixed boundary conditions for L introduce an ambiguity.
Consider:

L = [[1.0, x, x],
     [  0, 0, 0],
     [  0, 0, 0]]
P = [[x, 0, 0],
     [x, x, x],
     [x, x, x]]

What we need is F^(n+1)=F_dot^(n+1) x Delta_t, where F_dot^(n+1) is
F_dot^(n+1)_ij = L_ik F^n_kj.

So component F_11 has contributions from L_12 and L_13. We first assume
L_12=L_13=0 and then choose F^(n+1)_12 and F^(n+1)_13 to get
P_12=P_13=0. This implicitly gives a solution for L_12 and L_13, which
is however only one out of infinitely many.
