Can you show us the mesh in this section.
The mesh is the following:
I understand that maybe the mesh should be more refined in the near wall region, but the mesh as it is is consuming almost All RAM from my computer. We're talking 8GB of RAM. And on the other hand, I can't use a coarser mesh in other regions because there are concentration gradients at the center that I need to capture well. Using point parameters, I managed to pick a couple of points and replicated what the XY plot is trying to do. This is what I came up with:
If you don't consider the scale, wich is obviously diferent, you can see that this graph is exactly the same, but with no zero velocities in the near wall region. Naturally this go round method would do the trick, but using XY plots is much much faster and I have plenty of mixers to simulate, and plenty of diferent flows each. So it's clear that If I can use a method that reduces the time I spend treating results, it would be very nice.
