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

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
