Spincfd,

Have you checked which window the data should appear in? You should find it in monitors window. Make sure you choose the same window as specified in the monitors tab and "Print to console" is activated. Otherwise you may have the blank window.

The sencond one is to set up the transient simulation iterations. You can choose how many iterations per timestep, how many timesteps and the size of the timesteps.

This is to set the iterations of the solver, nothing to do with animation.
How to do the transient iteration?

Go to general tap (on left side) and choose transient. Now go to calculate panel and give the time step size and total time steps.

I am sorry as the video resolution is too small and can not be viewed.

I am trying to upload better video resolution.

It doesn't looks like Fluent 6.2.16.

Also, it looks like you are using a Mac.

Compare yours with mine.

Go to the general tap?

Perhaps tab.

There is no general tab in Fluent 6.2.16.

Define - Model - Solver
Where you see Time choose unsteady (unsteady - transient means the same)

You can find this in Solve - Monitors - residuals
See step 4 here:
http://cdlab2.fluid.tuwien.ac.at/LEH.../tg/node61.htm
On the top right corner, in Plotting square you can choose the windows where to show your monitors.

Be sure you are recording each frame of your animation, you will have a file for each one. If you don't have this you might have not set the animation properly and that why you can't watch it.

Why I should choose the unsteady if I want the steady and laminar flow?

What I understand is, you tell me to check/choose the unsteady option if I want to iterate as a time step instead of number of iteration, am I right?

I don't do this step before the blank problem appears but the display shows the animation very good.

I have a laptop, the blank display also happen in my laptop.

I can see all of the files associated with the animation for every frames.

A lot of files.

There are two types of file.

.hmf and .ppm

What software to open them?

And how do I know if them is okay or not?

ppm are portable pixel map. I've opened them with photoshop, but I'm sure there are other softwares.

With correct I mean if there's something on those images or they're blank.

I open one of them, the .ppm file, in the Adobe Photoshop and you are absolutely correct.

The image shows blank.
