Premixed Combustion in Star CCM+
Hi, I am an undergraduate student using Star CCM+ for my project. My Project involves premixed combustion using an EBU model. The problem is that I can't define the density of the body being used, I am using a field function to define the regress variable and the fuel mixture contains CH4 and Air. When ever I try to initialize the problem the software gives me a floating point error saying

"Initializing turbulent flow with density unavailable in Body 1 3!
** Density of 1 kg/m^3 assumed for computing initial turbulence quantities."

Can any one please help me with that.

Thank you
