I hope to simulate flow enters the pipe. I want to show velocity profile with the time in the pipe.
How can I select time step and physical time for the unsteady problems?
Is the solution for every time step reach to conversion?
You can try project > wizard > analysis type > time dependent, and enter total analysis time and time step.
thanks for your quick response
I know how to solve unsteady, but I want to know how to select time step, and How can I see the results after certain time?
Results are saved by iteration number r_000xxx.fld where the last 6 digits is the interation number. Each time step that was saved was done at a particular interation number. The command "Load Time Moment" seen in the picture below can help facilitate doing this.
yes ,you can plot the output wrt to time in the TIME HISTORY, by selecting the particular point/face/volume parameters as shown below
select the time steps in TIME HISTORY wherever you would like to plot
Dear Joe Galliera, I have problems with a trasient analysis that always the iteration number r_000xxx.fld shows zero r_000000.fld, do you have idea why this?
r000000.fld is the initial conditions. The final conditions are saved in the final results file (folder #).fld If you tell it to save intermediate results you will have other files r000543.fld, etc.
The calculation control options let you specify which time steps you want to save.
A lot of thanks, please could you tell me? which parameters I put, to save intermediate values, here
With what you have shown it will start saving at 0 seconds and save the results every 1 second.
You need to make sure that on the "Finish" tab you have selected conditions that allow it to run long enough to capture that data. If you limit it to 4 travels (default) and have a fast flow, it might achieve 4 travels before 1 second and you would not have any intermediate data. You would be best to clear all of the Finish settings except for the total simulated time.
For a transient solution, travels is automatically not selected (pretty sure of this off the top of my head), but if it is then as Chris suggested turn it off.
thanks AMIGO Chris, for the information and got the data I wanted
Muchas gracias Estimado Chris
