[pramodopen4foam]

Hi friends,
I tried to merge solvers settlingFoam and bubbleFoam, then when I ran wmake command I got error messages as follows :
"In file included from comsol.C:38:
calcVdj.H:1: error: ‘VdjModel’ was not declared in this scope
calcVdj.H:3: error: ‘Vdj’ was not declared in this scope
calcVdj.H:3: error: ‘V0’ was not declared in this scope

calcVdj.H:11: error: ‘a’ was not declared in this scope
calcVdj.H:21: error: ‘Vdj’ was not declared in this scope"

can anyone help me as I am very new to C++ programming,
does these errors mean my equations are not consistent ?,

Thanks in advance
