Hi, How can we store a variable value for a particular point in the domain, at different time steps? The CFX-Pre stores the variable values for all points.

Thanks

User fortran. Create your own variables. Read the "Memory management" section of the manual.

What exactly are you trying to do?

I have to store the values of pressure and velocity, only at a point (monitor point) on the axis at the inlet of a nozzle for each timestep. So that i can plot the variables with respect to time. I think that values at monitor points(created) will not be stored for post processing. Values are stored for the whole domain and it amounts to lot of memory.

Values at monitor points are stored to the MON file at every iteration. At the end of the run, the mon file is embedded into the res file (which is in fact an archive). When you open the RES file in the Solver Manager, it plots the contents of the MON file.

So... create your monitor point and monitor the data you are interested in. After the run has finished, right click on the plot in the Solver Manager and you can output your data to a .csv file.

Just keep in mind that if you do not include the trn files and you see something interesting in the monitor data, you will not be able to go back and view the results at those timesteps. At the very least, I recommend calculating transient statistics.
