ConjugateInterHeatFoam in OF.1.6-ext..need help to fix the error!!!
 
Hello Guys,

I modified the conjugateHeatFoam solver in OF.1.6-ext to couple my interHeatFoam solver with solid part. I managed to compiled the solver without problem. But When I am trying to run it in a case of droplet impact on hot surface, it shows me this error:
*******************

// using new solver syntax:

{

I think this error comes from CreateField file, So I bring it here for you guys to see if any parts of it need to be fixed.
