I-OpenFOAM: Umthombo Ovulekile we-Computational Fluid Dynamics

I-OpenFOAM Kuyinto a Ithuluzi lamathuluzi (I-ToolBox) ngo- Umthombo Ovulekile futhi ihlelwe, isetshenziswe kufayela le- Amandla we-Computational Fluid Dynamics (Amandla weComputational Fluid - CFD).

Ngaphandle kokuvuleka, kubuye futhi mahhala futhi idalwe yi Isisekelo se-OpenFOAM. Futhi isatshalaliswa kuphela ngaphansi kwe- Ilayisensi Yomphakathi Jikelele (GPL), ukuze kuzuze bonke.

I-OpenFOAM ikhethe ilayisense le-GPL ukunikeza abasebenzisi bohlelo, i- inkululeko yokuguqula nokusabalalisa kabusha isoftware kanye nesiqinisekiso sokuqhubeka nokusetshenziswa kwamahhala, ngokwemigomo yelayisense. Ukwenza okufanayo, a okunye okuhle kakhulu kulo mkhakha ngokumelene nezixazululo zobunikazi, ezivaliwe nezokuhweba.

Kumele uqaphele lokho I-OpenFOAM yadalwa futhi yakhululwa yisakhamuzi UHenry weller, ngonyaka 1989, ngaphansi kwegama le- "FOAM»Futhi yashicilelwa njenge«I-OpenFOAM"ngu UHenry Weller, uChris Greenshields noMattijs Janssens, ngoDisemba 2004. Kusuka lapho, I-OpenFOAM iqhubekile nokuphathwa futhi yathuthukiswa ngezinguqulo ezintsha ezikhishelwa umphakathi minyaka yonke. Futhi inguqulo yakamuva ezinzile ekhishwe yinombolo 7.

I-OpenFOAM: Vula i-ToolBox yama-CFD

Yini i-Computational Fluid Dynamics?

Ngokusho kwe- Ibhulogi ye-ESSS, iwebhusayithi ekhethekile odabeni, kulokhu isihloko, Lokhu:

"IComputational Fluid Dynamics noma i-CFD (i-Computational Fluid Dynamics) iyindawo yolwazi ebhekana nokulingiswa kwamanani okugeleza koketshezi, ukudluliswa kokushisa nezinye izinto ezihlobene nokuhlangana kwamakhemikhali, amandla omlilo, i-aeroacoustics njll. I-CFD iqhamuke ekuhlanganisweni kwemikhakha emibili: imishini eketshezi kanye ne-calculus yezinombolo. Izibalo ezilawula ukugeleza koketshezi zinomsuka wazo kumishini eketshezi futhi zingaxazululwa ngezindlela ezahlukahlukene zokubala".

"IComputational Fluid Dynamics isetshenziswa kabanzi ezigabeni ezahlukahlukene zomkhakha futhi isekela ukwakhiwa nokwenziwa kwamakhulu emikhiqizo, njengezindiza, izimoto nemikhumbi, kanye nezinhlobo ezahlukahlukene kakhulu zemishini yezimboni. IComputational Fluid Mechanics ingasetshenziswa kusuka esigabeni somqondo sephrojekthi, isiza ukuthola ukuthi kungenzeka yini kanye nesixazululo esihle somkhiqizo, kuze kufike esigabeni sokukhiqiza, kuvumela ukumelwa kwezimo ezahlukahlukene".

Iziphi izici i-OpenFOAM enazo?

I-OpenFOAM inebanzi ububanzi bezici. Phakathi kwalokhu singabala:

• Ikhono lokulingisa noma yini ehlobene nendawo ye-CFD, efana noku: Ukugeleza kwesiphithiphithi ku-aerodynamics yezimoto, kuze kufike emlilweni nasekucindezelweni komlilo ezakhiweni, okubandakanya ukushisa, ukusabela kwamakhemikhali, ukudluliswa kokushisa, okufafaza uketshezi namafilimu .
• Kubandakanya amathuluzi wokungena ngaphakathi nangaseduze kwamajometri ayinkimbinkimbi (isb. Imoto), nokucutshungulwa kwedatha nokubukwa, phakathi kwabanye.
• Qalisa izibalo ezihambisanayo njengezinga elijwayelekile lokusebenzisa ngokugcwele amaprosesa anamuhla ama-multi-core kanye nama-computer ama-processor amaningi.

Ezinye izici zobuchwepheshe ezizogqanyiswa yilezi:

I-Fluid Dynamics / Imodeli Yomzimba

• Ukumodeliswa kwesiyaluyalu
• Ukumodeliswa kwe-Thermophysical
• Ezokuthutha / iRheology
• Nokunye okuningi

Ukuhlaziywa kwedatha

• Ukucubungula ngemuva kwe-ParaView
• I-Post-Processing Command Line Interface (CLI)
• Idatha yokufaka igrafu nokuqapha

IJiyomethri nemeshi

• Ukwenza i-Mesh kwama-geometri ayinkimbinkimbi ane-SnappyHexMesh
• Ukwenza i-Mesh kwama-geometri alula nge-blockMesh
• Amathuluzi wokuguqula i-Mesh
• Amathuluzi okuphatha i-Mesh

Isixazululo samanani

• Indlela yezinombolo
• Linear System Solvers
• Izixazululo zesistimu ye-ODE

Computing kanye noHlelo

• I-syntax syntation
• Imitapo yolwazi yomsebenzi
• Ikhompyutha efanayo

Ingatholakalaphi i-OpenFOAM?

Iwebhusayithi esemthethweni ye- I-OpenFOAM YisiNgisi kodwa ine enembile kakhulu futhi kulula ukuhlola interface. Ibuye inezinye izingosi ezisizayo ezinolwazi oluningi. Ngemuva kwalokho okufanayo:

• Iwebhusayithi Esemthethweni
• Sourceforge
• I-CFD Direct

Isiphetho

Siyethemba ukuthi lokhu "okuthunyelwe okuwusizo okuncane" mayelana «OpenFOAM», okuyinto a «Caja de Herramienta (ToolBox)» de umthombo ovulekile futhi ungahleleka yokufunda i «Dinámica de Fluidos Computacionales (Computational Fluid Dynamics - CFD)», yiba nentshisekelo nokusetshenziswa okuhle, kwayo yonke «Comunidad de Software Libre y Código Abierto» kanye negalelo elikhulu ekusabalalisweni kwesimangaliso semvelo, esikhulu futhi esikhulayo sokusebenzisa kanye nokwenzelwe «GNU/Linux».

Futhi ukuthola eminye imininingwane, unganqikazi njalo ukuvakashela noma yikuphi Umtapo wolwazi oku-inthanethi njengoba I-OpenLibra y I-JedIT ukufunda izincwadi (ama-PDF) ngalesi sihloko noma ezinye izindawo zolwazi. Okwamanje, uma ukuthandile lokhu «publicación», ungayeki ukuyaba nabanye, ku- Amawebhusayithi ayizintandokazi, iziteshi, amaqembu, noma imiphakathi zokuxhumana nabantu, okungcono mahhala futhi evulekile njenge I-mastodon, noma ukuphepha nokuyimfihlo kwangasese yocingo.

Noma mane uvakashele ikhasi lethu lasekhaya ku- DesdeLinux ukufunda okunye okuthunyelwe okuthakazelisayo mayelana «Software Libre», «Código Abierto», «GNU/Linux» nezinye izihloko ezihlobene ne- «Informática y la Computación»kanye «Actualidad tecnológica».
