    Smile OpenFoam နဲ႕ပတ္သက္၍

    OpenFoam က CFD tool တစ္မ်ဳိးပါပဲ။ C++ အေပၚမွာ အေျခခံထားပါတယ္။ CFD ေတြမွာ Computation Code ေတြကို Fortran, C or Mathlab ေတြသံုးျပီး ကိုယ္ပိုင္ေရးရင္ေရး၊ ဒါမွမဟုတ္ Fluent, Star CCM ေတြလိုမ်ဳိး Commercial Code ေတြကို ၀ယ္ျပီး သံုးရင္သံုး ဆိုျပီး ရွိပါတယ္။ OpenFoam ရဲ႕ အားသာခ်က္ကေတာ့ Code ေတြေရးရသလိုလည္း မခက္ခဲသလို ၀ယ္ျပီးလည္း သံုးစရာမလုိပါဘူး။ သူက Open Source ပါ။ ၾကိ္ဳက္သလို ယူသံုးႏိုင္ပါတယ္။

    သူက Linux os သံုးျဖစ္ပါတယ္။ Linux ရဲ႕ သေဘာက command line ေတြအဓိကထားျပီး သံုးရတာမို႕ Linux နဲ႕ေတာ့ ရင္းႏွီးဖို႕လိုပါတယ္။ ကြန္ပ်ဴတာတစ္လံုးမွာ Window နဲ႕အျပိဳင္ linux os တစ္ခုခုတင္ထားႏိုင္သလို Window ထဲမွာကိုပဲ Virtual Box သံုးျပီးလည္း တင္ႏိုင္ပါတယ္။ အဆင္ေျပသလို သံုးႏိုင္ပါတယ္။ Linux မွာလည္း အမ်ဳိးအစားေပၚမူတည္ျပီး OpenFoam ကလည္း ကြဲပါတယ္။ ကၽြန္ေတာ္က Ubuntu ကိုသံုးေလ့ရွိတာမို႕ Ubuntu version ကိုယူေလ့ရွိပါတယ္။ သြင္းရတာလည္း မခက္ခဲပါဘူး။ အသံုးျပဳတာ လက္ယဥ္ဖို႕ေတာ့ က်ဴတိုရီယယ္နာနာလုပ္ဖို႕လိုပါတယ္။ (CFD သမားေတြကိုေျပာတာပါ)

    ကၽြန္ေတာ္တို႕ Code ေရးရင္ တစ္ခုခုကို ဆြဲသံုးခ်င္ရင္ Function, Subroutine တစ္ခုခုသတ္မွတ္ျပီး အဲဒီမွာ ကုဒ္အျပည့္ျပန္ေရးရပါတယ္။ OpenFoam ရဲ႕အားသာခ်က္က Library ေတြရွိပါတယ္။ တခုခုလိုခ်င္ရင္ ဆြဲသံုးလိုက္ရံုပါပဲ။ ဒါေၾကာင့္ အေတာ္သက္သာပါတယ္။ စိတ္ပါ၀င္စားတယ္ဆိုရင္ စမ္းသံုးၾကည့္ေစလိုပါတယ္။ ကိုယ္ေလ့လာလိုတဲ့ Geometry က ရွင္းရွင္းေလးဆိုရင္ အဆင္ေျပပါတယ္။ Flow in the pipe လိုမ်ဳိး၊ NACA Profile ေတြလိုမ်ဳိး၊ ေနာက္သေဘၤာမွာဆိုရင္ Wigley Hull လိုပံုစံမ်ဳိးဆိုရင္ လြယ္လြယ္ကူကူ ေလ့လာႏိုင္ပါတယ္။ သေဘၤာမွာေတာ့ နည္းနည္းရႈပ္တဲ့ Hull Type မ်ဳိးကိုေတာ့ ကၽြန္ေတာ္လည္း မစမ္းဖူးေသးေတာ့ မသိေသးဘူး။ ခုေလာေလာဆယ္ OpenFoam ထက္ တျခားကုဒ္ေတြကိုသံုးျပီး လုပ္ေနရတာမို႕ OpenFoam ဘက္မလွည့္ႏိုင္ေသးတာပါ။ သူငယ္ခ်င္းတို႕ စမ္းသပ္လို႕ရရင္လည္း လက္တို႕ပါဦး။ OpenFoam ေတြကို ေလ့လာဖို႕ ေအာက္ကလင့္ခ္ထဲမွာ OpenFoam software, tutorial အကုန္ရွိပါတယ္။ အဆင္ေျပပါေစဗ်ာ။

    Osaka က CFD ဆရာ ဖုိရမ္မွာ ဆက္ေရးပါဗ်။ ၾကိဳဆုိပါတယ္။
    အခုေလာေလာဆယ္ CFD code အေၾကာင္းေရး၊သိႏုိင္တဲ႔ သူမ်ိဳးက ကုိ NayYanNaing နဲ႔ ႏုိင္ငံျခားျပန္ဆရာ၊ဆရာမ အခ်ိဳ ႔ဘဲ ရွိႏုိင္မယ္ထင္တယ္။
    ဘာပဲေျပာေျပာ က်ေနာ္တုိ႔အဖုိ႔ ၾကားဖူးနား၀ေလာက္ရွိထားရင္ကုိဘဲ အက်ိဳးရွိလွပါျပီ။

    က်ေနာ္ OpenFoam သုိ႔မဟုတ္ CFD Software တစ္ခုခုထဲမွာ NACA profiles ေတြကို Analysis လုပ္ခ်င္ပါတယ္။
    လုပ္ဖူးသည္မ်ားရွိၾကရင္ မ်ွေဝေပးၾကပါဦးဗ်ာ..

    Viscous flow ထဲမွာေတာ့ မလုပ္ဖူးဘူးဗ်။ Potential flow မွာေတာ့ Joukowski Wing အတြက္ေရးထားတာေတာ့ရွိတယ္။ တိုတိုေလးဆိုေတာ့ Fortran နဲ႔ပဲ ေရးလိုက္ပါတယ္။ ရိုးရိုး NACA အတြက္လည္း Potential Flow ပဲရွိတယ္ဗ်။

    Is this version 2.4.6 is compatible with fluent 6_2_16? I got some problems with license file and I think it is not compatible?
