Hi,

I am trying to do a 2D axisymmetric flow analysis. I am facing with an issue in fluent where it shows an error saying: "Invalid axisymmetric mesh with nodes lying below the x-axis".
But I am sure that my geometry ends on the x-axis and there is nothing below it. I have attached pictures for reference. You can also check the mesh that I have made.
Kindly advice on How to solve this?

Thankyou

Edit: I have found in mesh check fluent says under Domain Extents: that my geometry starts from negative y-coordinates. So I presume that somehow some of my geometry is below x-axis (no idea how). And the solution was to move my mesh up so that nothing is below x-axis. To move it up it seems I have to use some commands like fix mesh, or mesh translate, Both of which I do not know how to do. Since I am new to this I kindly ask for guidance with steps as to how to use these commands in fluent, what to type exactly in the console command window to move my mesh up.

Thankyou.

Thank you, I found it.
In order to set my lower edge boundary as axis, is there any rule that whatever edge I'm setting as axis should be exactly on the x-axis? Or can it be a little away above the x-axis and not exactly on it?
