i want to export the pressure signal at every nodal point from my trn file a particular timestep. later i want to do the same for all the timesteps in one pitch. can anyone tell me if it is possible to extract nodal from trn files and how? Thank you.

Yes, you can do this. Save trn files at all the time steps you want the data, then in CFD-Post use file/export to export the pressure data. For the run where you want a lot of time steps you can use a session file to automate the process.
