Hi.I want to run and analyse a pipe flow problem using simpleFoam solver in openFoam v6.0... I`ve created a mesh by blockMesh and check its quality but when I call simpleFoam in terminal ,confronted by this error...Does anybody can help me on this issue?!

Have you done any tutorials?
Did you actually read the error message?

Go to your fvSchemes and find the line:
div((nuEff*dev(T(grad(U))))) Gauss linear;
Add the line that OF is looking for with an appropriate scheme underneath:
div((nuEff*dev2(T(grad(U))))) Gauss linear;
Just about everyone on this forum has run into this, I'm sure you could have found the solution with more searching.

you are right.I got a bit rushed and realized the problem quickly by reading the error.
