Version 3.1.2 (2003/07/09)
Interim release enhancements
Additional refinements to 2D graphics:
rework of SciPlot numerics to correct problems that were occurring when the y axis values become too large and/or when a range is not yet available:
switched x and y axis numeric labels from a “%f” fixed format to a “%g” output format which automatically switches to exponential format when the numbers become large. This format also allows for minimal label precision and field width.
reworked numerics for calculating axis increments and estimating space allocation for the new numeric label formats.
reduced the maximum number of x axis increments to eliminate some label overlapping and centered the x axis labels on the axis ticks.
addition of plot window options for axis labels and legends.
min/max symbols changed to unique shapes (discernable in black/white EPS).
thumb wheels now support bidirectional windowing (left or right and up or down).
refinement of initial graphics window sizing for larger numbers of plots.
elimination of some data skipping in the graphics through suppression of data sets which contain only derivative data.
efficiency enhancements through removal of redundant arrays and streamlining of data updates.
initial release of DPREPRO (DAKOTA pre-processor), a freely-distributable pre-processor for use in interfaces between DAKOTA and various simulation codes. DPREPRO is a Perl script utility that inserts values from the DAKOTA parameters file into a template simulation input file to create new simulation input file instances. Features include:
supports both APREPRO and standard formats in the DAKOTA parameters files and auto-detects the format in use.
extracts variable assignments both from the parameters file and from the template file and supports multiple order-independent matches and replacements per line.
stores tag/value pairs in a hash for lookup efficiency.
supports algebraic manipulation using both the intrinsic Perl functions as well as a variety of additional math subroutines.
fixed a bug with management of the aprepro format for LayeredModels which was occurring in hierarchical surrogate-based optimization.
added a workaround for older pgf90 compilers such as those used on ASCI Red to allow use of the new f90 LHS library within DAKOTA. To mix C++ with pgf90, an explicit call to pghpf_init() is needed to allow f90 calls to ALLOCATE().
