ip volume is now based on the determinant of F. "mesh_ipVolume" represents the initial volume and is multiplied with det(F) wherever the current volume is needed. Since this works for all solver types, the "volume" output in crystallite is now also correct for spectral method and abaqus.

removed functions added for debugging of divergence calculation to math.f90
...
corrected calculation of stress BC condition. Depending on given BC, the stiffness matrix is reduced and than inversed. Then it is filled with zeros and used for the calculation of the correct change of deformation gradient. All calculation is done using dP/dF

Calculation of current ip volumes now working. Crystallite output also reflects current grain volume, not reference volume. However, this is only available for Marc. Abaqus and spectral method still return the reference ip volume. The ip coordinates though are correctly updated for all solver types.

added option to build DAMASK_spectral without openMP (make OPENMP=OFF)

fixed bug in bc_temperature assignment that was hitting memory.
Temperature is taken from the first loadcase and evolves from there in an adiabatic fashion for the moment. I.e. T-specifications from later loadcases are ignored...

Stress integration now uses Armijo rule to find an appropriate correction of Lp: decreases step in case that residuum does not improve significantly, accelerates as usual in case of good convergence. This turned out to improve convergence behavior.

* internal stress calculation now considers dead dislocations always at the interface, not at the center of the IP volume; used to merge them together with "normal" dislocations for stress calculation.
...
* dislocation flux is blocked if we encounter a sign change in the resolved shear stress from the central ip to the neighbor
* do not set density to zero if below certain threshold; this creates an artificial sink term

have to initialize constitutive_state during constitutive_init, since the first call to constitutive_microstructure (where we already need the state) is done before the cutback scheme starts.

some textconstants were wider than specified in the format string, this might have caused Abaqus to crash due to an illegal memory reference (signal 11)

restarting now works with Abaqus (standard, cannot test explicit due to lack of license)
...
you have to specify the job you are restarting from in the job description (cae), if you prepare your input file by hand this is the first line after *Heading
example: if the first job was using Oldjob.inp the first entry in the job description needs to be Oldjob (without the .inp)
as for Marc restart works only from last converged increment, i.e. ther restart writing should be specified like this:
*retsart, write, frequency=1, overlay
Overlay is not essential but saves a lot of disk space and as stated before you can only restart from the last converged increment anyway

56340fd487
changed input of loadcase. Now fdot (time derivative) can be used instead of velocity gradient. Velocity gradient needs to have each line fully or not at all defined, as for other loadcases the stress BCs are not known in advance. Also added the possibility to keep guessing along trajectory of former loadcase.
...
changed back to use the compliance of initial linear material behavior.
added counter of non-converged steps
renamed compiler flags in makefile

Ability to define loglinear time increments by using 'logincs' or 'logsteps' instead of 'incs' in loadcase file is added.

spectral solver can now write result at reduced output frequencies: use 'f', 'freq', or 'frequency' keyword in loadcase definition.
...
example: ... time 1 incs 100 freq 10 will write output at times 0.0, 0.1, 0.2, ... , i.e., every ten increments only.

ip coordinates are now updated every cycle; this is needed for the nonlocal internal stress fields
...
* Marc: node displacements are added to initial node coordinates (mesh_node0) to get current node positions (mesh_node), then ip coordinates are deduced
* Abaqus: ip coordinates are directly updated, no update of node coordinates!
* Spectral: for the moment no update of either ip or node coordinates! passing only dummy values with initial ip coordinates
