Lineær statisk analyse (elasticitet, parallel)¶
For at udføre statisk analyse (elasticitet) med 4-vejs parallel kørsel anvendes dataene i tutorial/02_elastic_hinge_parallel.

Analyseindhold¶
Pak FrontISTR-koden ud, gå til mappen for dette eksempel, og kontroller, at følgende filer, som kræves til analysen,
| Filnavn | Type | Rolle |
|---|---|---|
| hecmw_ctrl.dat | Overordnede styringsdata | |
| hinge.cnt | Analysestyringsdata | |
| hinge.msh | Meshdata | |
| hecmw_part_ctrl.dat | Styringsdata for meshpartitionering | Styringsdata, der bruges, når hecmw_part1 opdeler meshdataene i domæner |
er til stede.
Output:
Udfør en spændingsanalyse, hvor forskydningen af de fastholdte flader begrænses, og en koncentreret last påføres lastfladen.
De overordnede styringsdata, analysestyringsdataene og styringsdataene for meshpartitionering vises nedenfor.

Styringsdata for meshpartitionering hecmw_part_ctrl.dat¶
Analyseprocedure¶
For at køre FrontISTR med MPI opdeles meshdataene hinge.msh først i fire domæner.
Output:
Oct 07 11:04:52 Info: Reading mesh file...
Oct 07 11:04:52 Info: Starting domain decomposition...
Oct 07 11:04:52 TH(0/8) Info: Creating local mesh for domain #0 ...
Oct 07 11:04:52 TH(2/8) Info: Creating local mesh for domain #1 ...
Oct 07 11:04:52 TH(6/8) Info: Creating local mesh for domain #2 ...
Oct 07 11:04:52 TH(7/8) Info: Creating local mesh for domain #3 ...
Oct 07 11:04:52 Info: Domain decomposition done
Der genereres nye filer med navnene hinge_4.x og part.inp.
Output:
hecmw_ctrl.dat hecmw_part_ctrl.dat hinge.msh hinge_4.1 hinge_4.3
hecmw_part.log hinge.cnt hinge_4.0 hinge_4.2 part.inp
Kør derefter FrontISTR-programmet fistr1 med MPI.
(Kør med 4 MPI-processer og 1 OpenMP-tråd)

*.res.*-filer er resultatdata, der indeholder FrontISTR-analyseresultaterne for hver MPI-knude. De kan vises med REVOCAP_PrePost og lignende værktøjer.
*_vis_*-filer er visualiseringsdata og kan vises med generel visualiseringssoftware. I dette eksempel outputtes dataene i VTK-format, så brug ParaView eller lignende software til at vise dem.
