hey
I am new to openFoam. I am trying to solve flow through pipe with constant heat flux and constant wall temperature and got the answer but when I check i found that value of nu 0.01 but actual value of nu for water (kinematic Viscosity) is 0.000001 so I changed it and now m getting the answer. please help me to sort this out
I had modified icoFoam for solving this


thanks in advanced

icoFoam has the basic cavity tutorial case. This lid driven cavity tutorial was designed to look good and not to give the correct results. The case runs flawless with nu = 0.01 and gives nicer results in terms of colourful pictures. That's all
Why did you modify icoFoam instead of using buoyant solvers or use scalar transport on a converged flow field?

Cheers

thanks fabian for reply
actually I am new to openFoam and trying to solve various cases and I dont hv any idea about buoyantFoam that's y I modified icoFoam . now I had added temperature field in icoFoam and it is working fine.
thank you
