I'm guessing that the simulation is using no-slip boundary conditions (i.e. setting the velocity to be zero at walls). Are you sure that there should be non-zero velocity at the walls? Is there non-zero velocity elsewhere in the domain?<br>

<br>
I do an export from my CFD code using node-values. I get the value of<br>
"0" for the velocity at walls in Paraview. I can not visualise contour<br>
of velocity magnitude at the surface or do surfaces streamlines. How can<br>
I get velocities to wall boundaries? I tried calculation cell values and<br>
point values once again, however I still have zero velocites at walls.<br>
<br>
Thanks BastiL<br>
