PragTic¶
Introduction¶
PragTic is a freeware tool for an automated fatigue damage calculation based on a FE-solution or done at an isolated point with no relation to FEA. More details of PragTic are available on its [website][Welcome]. Here is the HPC version parallelized using MPI library.
Modules¶
PragTic version 0.1 is available on Salomon via the PragTic module:
$ ml PragTic
The module sets up environment variables and loads some other modules, required for running PragTic simulations. This particular command loads the default module PragTic/0.1-GCC-5.3.0-2.25 and modules:
GCCcore/5.3.0
binutils/2.25-GCCcore-5.3.0
GCC/5.3.0-2.25
MPICH/3.2-GCC-5.3.0-2.25.
Running¶
Follow the next step to compute simulations sequentially:
pragtic DATABASE ANSET SET_OF_POINTS LOAD_REGIME METHOD RESULT_FILE
and this step to compute it in parallel:
mpirun -np NP pragtic DATABASE ANSET SET_OF_POINTS LOAD_REGIME METHOD RESULT_FILE
where
| Parameter | Description |
|---|---|
| NP | number of processes |
| DATABASE | .fdb database specially prepared for PragTic |
| ANSET | analyse setup name |
| SET_OF_POINTS | set of points name |
| LOAD_REGIME | load regime name |
| METHOD | method name |
| RESULT_FILE | file where results will be saved |
Results¶
After computation, the newly created result file RESULT_FILE in the current directory should contain results. More detailed result informations should be found in the res.txt file which is in every single randomly named folder created by PragTic in the current directory.
