Greiningarniðurstöður¶
Þegar greiningunni er lokið verða til nokkrar nýjar skrár.
Úttak:
0.log hecmw_ctrl.dat hinge.res.0.0 hinge_vis_psf.0001
FSTR.dbg.0 hecmw_vis.ini hinge.res.0.1 hinge_vis_psf.0001.pvtu
FSTR.msg hinge.cnt hinge_vis_psf.0000
FSTR.sta hinge.msh hinge_vis_psf.0000.pvtu
*.res.*-skrár eru niðurstöðugögn sem innihalda greiningarniðurstöður FrontISTR. Hægt er að birta þær með REVOCAP_PrePost og sambærilegum verkfærum.
*_vis_*-skrár eru myndbirtingargögn og hægt er að birta þær með almennum myndbirtingarhugbúnaði. Í þessu dæmi eru gögnin skrifuð á VTK-sniði, svo nota skal ParaView eða sambærilegan hugbúnað til að birta þau.
Jafngildisspennulínurit von Mises sem búið var til með REVOCAP_PrePost er sýnt á mynd 4.1.3. Hluti annálsskrár greiningarniðurstaðna er einnig sýndur hér að neðan sem töluleg gögn úr greiningunni.
