solving natural convection problem
 

i have tried to solve natural onvection problem with star cd but the solution is not converging.

Re: solving natural convection problem
 

What is it doing? Diverging or oscillating? I would expect an oscillating solution, since very few natural convection problems are steady state in reality.

Which differencing scheme u have used? and which soln.algo u are using?

Re: solving natural convection problem
 

Do you use double precision, as recommended in User's Guide? Natural convection is driven by quiet small density difference, that's why you need double precision

Thank You all so much for your response

what are the conditions and how to solve a natural convection problem using star-cd???
any one help pls.....
