Hello All!

I am looking to get data for each time step at all the 10000 nodes of the meshing in Ansys Fluent. I need to monitor x-velocity, y-velocity, and vorticity around 2D circular cylinder. I do not know how to get that. Can somebody please help me with that...

I also write a journal file to create all these 10000 points in order to use surface monitors, but fluent showed some error due to a large number of nodes.

Thanks!

I suggest you to save your solution in ensight gold format, then you can use paraview to retrieve all the information you need.

Go to calculation activities and setup an automatic export during transient simulation.

Do not select any surfaces! Choose nodes if you want nodes, leave empty if you want cell centers.

Choose your export format, ascii if you don't have a preference.

If you do not choose any surfaces, it will write at every single cell in the domain. If you choose any surfaces, it will write only on the surface and not the domain.

Choose all the variables you want (velocity, etc.). You do not need to select x,y,z coordinates. The x,y,z locations will always get written.

Thanks! It really helps me a lot and saves me a lot of time.
