2013-01-21 21:57:26 +00:00
Philip Eisenlohr 1e32eb560e corrected buggy calculation of Schmid matrix for twins introduced in rev1809.

Martin Diehl 800e291240 made code standard conform to Fortran 2008 (ignoring warning concerning comments beyond character 132). Basically, changing "x" format specifier to "Nx" ("1x") plus removing $ format specifier
added compiler switches for gfortran and ifort to check for standard conformity
old gnu compilers <4.4 are not longer supported because they don't provide the c binding for fftw
2012-01-31 19:18:55 +00:00

2012-01-31 14:54:49 +00:00
Christoph Kords 1330576a01 added new math function "math_deviatoric33" which returns the deviatoric part of a 3x3 tensor
renamed some math functions, so that we have a universal naming scheme: for matrix multiplications use an "x" (e.g. math_mul33x3); don't use the "x" to describe the shape of the tensor that the function is applied to (e.g. math_invert33 instead of math_invert3x3)

Philip Eisenlohr a7d9d711f6 edited lines exceeding 132 chars (before any comment started) 2012-01-11 16:56:35 +00:00
Martin Diehl c35ea33f8e did a lot of polishing:
- removed unnecessary "return" before end of subroutine or function:
- changed undetermined array length (:) to (1:3)

To prevent problems with some code analysing tools:
- "3D oneliner loops" (with ";) only for "do" and "enddo" at the same time
- removed line continuation in OMP statements

made the makefile more flexible, removed heap-arrays switch
2011-09-13 15:54:06 +00:00
Martin Diehl fe9754a41c previous commit was wrong file 2011-09-02 10:46:37 +00:00
Martin Diehl 43e2684cfb added new glide system for hex lattice 2011-09-02 10:43:49 +00:00
Martin Diehl 75c67f53f7 introduced alternative location for material configuration.
If present, the >>>JOB.materialConfig<<< file takes precedence over the standard >>>material.config<<<
2011-08-02 10:14:16 +00:00
Franz Roters 7d84a0911e removed unused variables 2011-04-13 14:16:22 +00:00
Franz Roters c1b8391110 changed enconding of all source files to UTF-8 without BOM (signature) Codepage 65001 2011-04-07 07:20:28 +00:00
Franz Roters fcdb805225 added copyright text to all f90 (free) format files 2011-04-04 14:09:54 +00:00
Christoph Kords 11138e3ee2 debugging output is now controlled by the "verbosity" parameter in the debug.config ranging from 0 (=almost no output) to 8 (=very detailed output)
0 : only version infos and all from "hypela2"/"umat"
1 : basic outputs from "CPFEM.f90", basic output from initialization routines, debug_info
2 : extensive outputs from "CPFEM.f90", extensive output from initialization routines
3 : basic outputs from "homogenization.f90"
4 : extensive outputs from "homogenization.f90"
5 : basic outputs from "crystallite.f90"
6 : extensive outputs from "crystallite.f90"
7 : basic outputs from the constitutive files 
8 : extensive outputs from the constitutive files

If verbosity is equal to zero, all counters in debug are not set during calculation (e.g. debug_StressLoopDistribution or debug_cumDotStateTicks). This might speed up parallel calculation, because all these need critical statements which extremely slow down parallel computation.
2011-03-21 10:31:17 +00:00
Christoph Kords 235266b169 openmp parallelization working again (at least for j2 and nonlocal constitutive model).
In order to keep it like that, please follow these simple rules:

DON'T use implicit array subscripts:
example:    real, dimension(3,3) :: A,B
                  A(:,2) = B(:,1)               <--- DON'T USE
                  A(1:3,2) = B(1:3,1)       <--- BETTER USE
In many cases the use of explicit array subscripts is inevitable for parallelization. Additionally, it is an easy means to  prevent memory leaks.

Enclose all write statements with the following:
!$OMP CRITICAL (write2out)
<your write statement>
!$OMP END CRITICAL (write2out)

Whenever you change something in the code and are not sure if it affects parallelization and leads to nonconforming behavior, please ask me and/or Franz to check this.
2011-03-17 10:46:17 +00:00
Martin Diehl cd5407b08b removed all math functions only for double precision by the more flexible counterpart, e.g. "dsqrt --> sqrt", "dsin --> sin". Should not cause any harm, as long as "implicit none" is used.
Now it is possible to compile a single precision spectral solver/crystal plasticity by replacing mesh.f90 and prec.f90 with mesh_single.f90 and prec_single.f90.
For the spectral method, just call "make precision=single" instead of "make". Use "make clean" evertime you switch precision
