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. Here is HPC version which was parallelized using MPI library.

Modules

The PragTic, version 0.1 is available on Salomon via module PragTic:

$ 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, which is 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 newly created result file RESULT_FILE in the current directory should contain results. More detailed result informations then should be found in the file res.txt which is in every single randomly named folder created by PragTic in the very same current directory.
