I am doing a transient simulation in ANSYS Fluent. Setup in fluent (and hence computation) is done using double precision. However when I am writing the pressure data (for each time step) in a separate notepad file using console commands, I get a single decimal precision. How can this precision be increased? I see that when I export chart data from fluent in a CSV file for the same parameters, I get four digit precision after decimal.n

How are you writing the files? Generally, the monitor points are writing to the maximum precision level to the file.n

I am writing files using following console command:nplot plot y pressure y n n pressure y 1 0 wall_1 wall_2 ()n'pressure_file' is the name of the file and its storing pressure data on two walls viz. wall_1 and wall_2. This command is written under calculation activities, so it is executed at end of each time step.n

Are you exporting from the xy plots? Check the axis settings (via the GUI as it's easier) to see what's set, if anything. n
