Using the optimization scripts. Contact james.grogan@universityofgalway.ie for further details.
|
|
--------------------------------------------------------------
|
|
These scripts were developed to perform optmizations with Abaqus and DAKOTA on the ICHEC
|
|
system. With small modifications they can also be used to perform optimizations on
|
|
windows systems.
|
|
|
|
Prerequisites:
|
|
Abaqus (tested in v6.10)
|
|
DAKOTA (tested in v5.2) - needs to be built from source on ICHEC.
|
|
|
|
Sequence:
|
|
1. Launch.pbs
|
|
Sends optimization job to ICHEC queue. Loads modules neccessary for DAKOTA and runs the optimization job as
|
|
a taskfarm.
|
|
|
|
2. tasks.inp
|
|
Input file for the taskfarm program. Changes to a unique directory for each task an runs DAKOTA with the input file
|
|
OptB.in.
|
|
|
|
3. OptB.in
|
|
DAKOTA input file. Tells DAKOTA what sort of optimization to perform. How many parameters to use and what ranges the
|
|
parameters fall in. Launchs the preprocessing wrapper script 'PyWrapperB.py' and designates 'Bparams.in' and 'Bparams.out' as the optimization input and output files.
|
|
|
|
4. PyWrapperB.py
|
|
Python wrapper script. Launchs the Abaqus geometry kernel file 'OptB.py'. Launches each abaqus job. Launches the
|
|
postprocessor python file 'OptPostB1.py'.
|
|
|
|
5. OptB.py
|
|
Abaqus kernel script. Creates the FE model. Model parameters are read in from DAKOTA through the Bparams.in file.
|
|
|
|
6. OptPostB1.py
|
|
Post-processes the initial simulation. If a design looks promising it launches a corrosion simulation and a second postprocessor OptPostB2.py.
|
|
|
|
7. OptPostB2.py
|
|
Post-processes the corrosion simulation. Returns the objective function value to DAKOTA through the Bparams.out text file.
