Hi all!!
I have followed a tutorial by Martin Anderson (Chalmers). (http://www.tfd.chalmers.se/~hani/kur...ChangeFoam.pdf) I have modified everything according to his report and I was getting good results till the last step which is replacing the static saturation pressure to saturation pressure that varies with temperature.
Till now I am able to add temperature field to the solver but when I have replaced Psat with Psat (variable with temperature), I am getting a compilation error. (I just entered 'wmake' command)

Here is the output I am getting while compilation of code..,
I have also attached the screenshot.


Code:

What I understood was that alpha1_ is defined twice in the header files (twoPhaseMixture.H and interfaceProperties.H) that were included in mainsolver code (myInterPhaseChangeFoam.C) and alpha1_ is called next to these header files. Which means the next header file doesn't know which alpha1_ to use.
I am a beginner in programming. Please help me......
Thanks

Hi sherlock45,


Were you able to resolve this?

I was facing the same problem like OP and I wasnt able to explain this for myself, because in the more derivative class "immiscibleIncompressibleTwoPhaseMixture.H" was done basicly the same, just by having your class in between.


Long story short: Since the compiler is complaining about ambigiouity Iwas wondering why it worked for immiscibleIncompressibleTwoPhaseMixture.H I tried to put another class afterwards and THEN inherit from interfaceProperties and it worked.




My presumption in this case is, because both classes have defined alpha1_ and alpha2_ (one as variable (protected) the other as a const reference variable but as private member), normally I wouldnt expect any errors here but since there is an error.. yeah.. I believe there are two options to solve this problem: either by specifing which alpha is meant with twoPhaseMixture::alpha1_ or twoPhaseMixture::alpha1() or by putting a class before inheriting from interfaceProperties, where no member function is defined that wants access to a alpha value!
