hi,
I am simulating a wind pressure on a building,my inlet boundary conditin(u k ε) are not a constant,so I must write a new BC to my case,I have compile them (u k ε) successfully,so I follow the step 1.add libs ("libu.so") libs ("libk.so") libs ("libε.so") in my system/controlDict it is ok when I only add libs ("libu.so")in my system/controlDict,and I can calculate successfully, when I add libs ("libk.so"),it show --> FOAM Warning : From function dictionary::read(Istream&, const word&) in file db/dictionary/dictionaryIO.C at line 92 Reading "/home/ivan/OpenFOAM/ivan-1.4.1/run/tutorials/turbFoam/case1/system/controlDict" at line 28 could not add entry libs ( "libK.so" ); on line 28 of dictionary "/home/ivan/OpenFOAM/ivan-1.4.1/run/tutorials/turbFoam/case1/system/controlDict" entry already in dictionary : ITstream : /home/ivan/OpenFOAM/ivan-1.4.1/run/tutorials/turbFoam/case1/system/controlDict:: libs, line 27, IOstream: Version 2.0, format ASCII, line 27, OPENED, GOOD when I try to calculate,it is show: -> FOAM FATAL ERROR : gradientInternalCoeffs cannot be called for a defaultFvPatchField (actual type k) on patch inlet of field epsilon in file "/home/ivan/OpenFOAM/ivan-1.4.1/run/tutorials/turbFoam/case1/0/k" You are probably trying to solve for a field with a default boundary condition. From function defaultFvPatchField<type>::gradientInternalCoeffs( ) const in file fields/fvPatchFields/basic/default/defaultFvPatchField.C at line 694. FOAM exiting can someone give me a hand?I appreciate it.thank you. |
