Hi Jame,

In out file after the completion of the run you can get all such information including reynolds number. But better u calculate the local value at your required point using Reynolds no formula for pipe flows. (rho*U*D/mu)-----------Sheetalkumar

Thank you Sheetal and I don't know how i can use Relnolds number formulation CFX have this function?

thank you. Jame D.J.

I am looking in out file i seen Reynold number . I don't understand what point of this value ? Jame D.J.

Dear Jame, Go to tools and then variables. There u can define new function, provided u know expression for it in terms of already defined variables there. Take online help. Then u can fringe plot reynolds number throught pipe. ---- Sheetalkumar

thank you I will try follow your recommand.
