I-OpenFOAM: Umthombo ovulekileyo weComputerational Fluid Dynamics
I-OpenFOAM Yiyo Isixhobo sebhokisi (Isixhobo seBox) ngu Vula Umnikezi kwaye iyacwangciswa, isetyenziswe kwi Amandla okuChaphazela iiFluid Dynamics (IComputerational Fluid Dynamics-CFD).
Ngaphandle kokuba ivulekile, ikwanjalo mahala Kwaye yenziwe yi Isiseko seOpenFOAM. Kwaye isasazwa ngokukodwa phantsi kwe- Ilayisenisi Jikelele yoLuntu (GPL), ukuze kuzuze wonke umntu.
I-OpenFOAM ikhethe ilayisensi ye-GPL ukunika abasebenzisi benkqubo, inkululeko yokuguqula nokusasaza kwakhona isoftware kunye nesiqinisekiso sokuqhubeka nokusetyenziswa simahla, ngokwemiqathango yelayisensi. Ukwenza okufanayo, a enye indlela efanelekileyo kule ndawo ngokuchasene nezisombululo zobunini, ezivaliweyo nezorhwebo.
Kubalulekile ukuba uqaphele ukuba I-OpenFOAM yenziwe kwaye yakhululwa ngummi UHenry weller, enyakeni 1989, phantsi kwegama lika "I-FOAM»Kwaye yapapashwa njenge«I-OpenFOAM"nge UHenry Weller, uChris Greenshields kunye noMattijs Janssens, ngoDisemba 2004. Ukusukela ngoko, I-OpenFOAM iye yaqhubeka ilawulwa kwaye yaphuhliswa ngeenguqulelo ezintsha ezikhutshelwa uluntu minyaka le. Kwaye ingxelo yokugqibela ezinzileyo nenombolo 7.
I-OpenFOAM: Vula i-ToolBox yee-CFD
Yintoni i-Computational Fluid Dynamics?
Ngokutsho kwe Ibhlog ye-ESSS, iwebhusayithi ekhethekileyo kulo mbandela, koku nqaku, Yi le:
"IComputational Fluid Dynamics okanye iCFD (IComputational Fluid Dynamics) yindawo yolwazi ejongana nokulinganisa kwamanani okuhamba kwamanzi, ukuhambisa ubushushu kunye nezinto ezinxulumene noko njengokuphendula kwemichiza, ukutshisa, iaeroacoustics, njl. I-CFD ivela kwindibaniselwano yamacandelo amabini: oomatshini bamanzi kunye nokubala kwamanani. Amanani alawula ukuhamba kwamanzi anemvelaphi yawo kubuchwephesha bolwelo kwaye anokusonjululwa ngeendlela ezahlukeneyo zamanani".
"IComputational Fluid Dynamics isetyenziswa ngokubanzi kumacandelo ohlukeneyo emizi-mveliso kwaye ixhasa uyilo kunye nokuveliswa kwamakhulu eemveliso, ezinjengeenqwelo moya, iimoto neenqanawa, kunye nezona ntlobo zahlukeneyo zezixhobo zeshishini. IComputational Fluid Mechanics inokusetyenziswa ukusuka kwinqanaba lokuqonda leprojekthi, ukunceda ukumisela ukusebenza kunye nesona sisombululo semveliso, ukuya kwinqanaba lokuvelisa, ukuvumela ukumelwa kweemeko ezahlukeneyo".
Zeziphi izinto i-OpenFOAM enazo?
I-OpenFOAM ibanzi Uluhlu lweempawu. Phakathi kwezi sinokuzikhankanya:
- Ukukwazi ukulinganisa nantoni na enxulumene nendawo ye-CFD, enje: Ukuhamba okungxamisekileyo kwimoto yomoya, ukuya kwimililo kunye nokucinezelwa komlilo kwizakhiwo, kubandakanya ukutshisa, ukusabela kweekhemikhali, ukuhanjiswa kobushushu, ukufafaza ulwelo kunye neefilimu .
- Ibandakanya izixhobo zokungena ngaphakathi nakwiindawo ezijikeleze ii-geometri ezintsonkothileyo (umz. Isithuthi), kunye nokuboniswa kwedatha kunye nokulungiswa, phakathi kwabanye.
- Sebenzisa izibalo ezifanayo njengomgangatho wokusebenzisa ngokupheleleyo iiprosesa eziphambili zanamhlanje kunye neekhompyuter zeprosesa ezininzi.
Ezinye iinkcukacha zobugcisa ukuqaqambisa zezi:
Ulwelo lweDynamics / iModeli yePhysical
- Ukwenza imodeli yesiphithiphithi
- Imodeli ye-Thermophysical
- Ezothutho / iRheology
- Okuninzi nokuninzi
Uhlalutyo lwedatha
- IParaView emva kokuqhubekeka
- I-Post-Processing Command Line Interface (i-CLI)
- Igrafu yedatha kunye nokubeka iliso
IJometri kunye nemesheshi
- Isizukulwana se-Mesh sejometri ezintsonkothileyo ngeSnappyHexMesh
- Isizukulwana se-Mesh sejometri ezilula ezine-blockMesh
- Izixhobo zokuguqula umnatha
- Izixhobo zokuphatha umnatha
Isisombululo samanani
- Indlela yokubala
- Isisombululo senkqubo yomgama
- Isisombululo se-ODE
Ikhompyuter kunye neNkqubo
- I-syntax yokulingana
- Amathala eencwadi asebenzayo
- Ikhompyuter efanayo
Inokufunyanwa phi i-OpenFOAM?
Iwebhusayithi esemthethweni ye I-OpenFOAM Kungenxa yesiNgesi kodwa ine Intuitive kwaye kulula ukuyijonga ujongano. Ikwanazo nezinye iisiza ezincedisayo ezinolwazi oluninzi. Iyafana:
Isiphelo
Siyathemba ukuba yi "Uncedo oluncinci" ngaye «OpenFOAM», eyi «Caja de Herramienta (ToolBox)» de umthombo ovulekileyo kunye noqwalaselo yokufunda i «Dinámica de Fluidos Computacionales (Computational Fluid Dynamics - CFD)», Inomdla omkhulu kunye noluncedo, iyonke «Comunidad de Software Libre y Código Abierto» kunye negalelo elikhulu ekusasazekeni kwendalo emangalisayo, enkulu kunye nokukhula kwezicelo kunye «GNU/Linux».
Ngolwazi oluthe kratya, sukuhlala ungathandabuzi ukutyelela nayiphi na Ilayibrari ekwi-Intanethi njengaye VulaLibra y IJedIT ukufunda Iincwadi (iiPDF) kwesi sihloko okanye abanye iinkalo zolwazi. Okwangoku, ukuba uyithandile le «publicación», Sukuyeka ukwabelana ngayo nabanye, kwi Iiwebhusayithi ozithandayo, amajelo, amaqela, okanye uluntu zonxibelelwano zentlalo, ngokukhethekileyo zisimahla kwaye zivulekile njenge IMododon, okanye ukhuselekile kwaye uyimfihlo ngathi yocingo.
