[Fluent] Problem in Mach Contours
 

I have a problem in viewing Mach contours on the body (wall), everything is blue, showing very low mach number.

I am running CFD simulation at:

M =1.0, and 1.5
Ansys Fluent 13 & 14

Mesh was created in Ansys Meshing and ICEM.

Pressure contours are very fine on the body.

Contours of Mach in the farfield region are quite good.

Kindly help me, what and where is the problem?

It's obvious, you use no-slip wall boundary conditions, velocity of wall and in vicinity is zero.

you are right. but in previous versions of fluent like 6.3, Mach contours can be seen.

I am saying Mach number, not the velocity magnitude.

Velocity magnitude will off-course be 0.

Ma = V/c
The none zero value of Mach number on wall you saw may be cell value, not node value.

Thanx.

Is it possible if my first node is far from the wall (away from the boundary layer). The Mach number shown on the wall is actually the value of that cell?
