Hi. I am doing my thesis On Modal Flows of Fluid Flows. I have run my simulation for cylinder 2D in ANSYS 17.1 with a reynolds number of 80. The Von Karman vortices are developed which need to be analysed in MATLAB for its energy nodes and eigen vectors.

My problem is that I have read a lot of articles regarding POD which they use the snapshot method. I tried exporting my data as ASCII from ANSYS which gives me the nodes with X and Y coordinates along with its Velocities. I am just wondering how do I export my data for each second into MATLAB which makes sense like a snapshot method. I have spent some time on the forum but just getting lost. Please need help urgently.

What software do you use? CFX or Fluent?

For example in Fluent you would go to File=> export => solution data during calculation

Having the right title would help. Your question is really how to export data and nothing to do with POD. Posting in the right forum certainly helps to get a response. Ask a mod to move it for you.

My question is how to export the data from FLuent ansys using ASCII for all the time steps. Cuz when I export it, it only gives me the 1 time. I want the data for all the time. And once I export it in nice rows and columns, I want to use that for POD analysis
