From 64435b8a97f7b5c4ae26a94ae5305cca7f643ed8 Mon Sep 17 00:00:00 2001 From: Onur Guevenc Date: Tue, 2 Aug 2011 13:58:28 +0000 Subject: [PATCH] loadcase takes 'temperature' (or 'temp') as input. Previously it was hard-wired. --- code/DAMASK_spectral.f90 | 34 ++++++++++++++++++++++------------ 1 file changed, 22 insertions(+), 12 deletions(-) diff --git a/code/DAMASK_spectral.f90 b/code/DAMASK_spectral.f90 index 10d3b9d7e..acc1eb540 100644 --- a/code/DAMASK_spectral.f90 +++ b/code/DAMASK_spectral.f90 @@ -63,7 +63,7 @@ program DAMASK_spectral integer(pInt), dimension (1+maxNchunksInput*2) :: posInput integer(pInt), parameter :: maxNchunksGeom = 7 ! 4 identifiers, 3 values integer(pInt), dimension (1+2*maxNchunksGeom) :: posGeom - integer(pInt) unit, N_l, N_s, N_t, N_n, N_freq, N_Fdot ! numbers of identifiers + integer(pInt) unit, N_l, N_s, N_t, N_n, N_freq, N_Fdot, N_temperature ! numbers of identifiers character(len=1024) path, line logical gotResolution,gotDimension,gotHomogenization logical, dimension(9) :: bc_maskvector @@ -72,7 +72,8 @@ program DAMASK_spectral real(pReal) time, time0, timeinc ! elapsed time, begin of interval, time interval real(pReal), dimension (:,:,:), allocatable :: bc_deformation, & ! applied velocity gradient or time derivative of deformation gradient bc_stress ! stress BC (if applicable) - real(pReal), dimension(:), allocatable :: bc_timeIncrement ! length of increment + real(pReal), dimension(:), allocatable :: bc_timeIncrement, & ! length of increment + bc_temperature ! isothermal starting conditions integer(pInt) N_Loadcases, step !
