Extract field data in tecplot over time

Hello everyone,

I'm going to prepare some data for machine learning. To this end, I need to get field data such as pressure and velocity over time for all cell centers.

However, I have simulated my problem in Fluent Unsteady. So, how can I extract the field data in tecplot over time?

In tecplot I follow up these procedures:

create macro
load data
create rectangular zone
interpolate data to the zone
and finally write the data

All are good, except third step, where I should define I and J numbers.
How can I extract data for all cells over time respectively?
Thank you.

PyTecplot is a great way to grab raw data from Tecplot 360.

If the data are already cell-centered, simply grab and array of data using the following PyTecplot (python code)

Code:

import tecplot as tp

from tecplot.constant import *

dataset = tp.active_frame().dataset



# Get an array of Pressure values for the first zone

zone = dataset.zone(0) # zone numbers are zero based in PyTecplot

variable = dataset.variable("Pressure")

values = zone.values(variable)[:]



# Loop over all zones and all variables, getting the cell-centered data values

for z in dataset.zones():

    for v in dataset.variables():

        var_values = z.values(v)

        if var_values.location == ValueLocation.CellCentered:

            cc_values = var_values[:]

            # Do something with cc_values
