Hi All

Does anyone of you help me with telling the steps to give to save the instantaneous files in Starccm+ during an unsteady simulation. I couldnt find it in the tutorials as far as I searched. I want to save the .trn files every 100 or 500 iterations so that I can check the instanteneous results and also average it for a particular time. Thanks in advance.

The best way to save data is using reports, monitors, probe points, others. There is post processing tutorials for this or should be at this point.

Sorry my question was how to save the instantaneous files of my pressure drop, velocity etc in a flow. As I am doing transient simulation I need to see my Instanteneous results during every 1000 iteration or every 1 physical second. So I need to save them. This was my question. (For example in CFX you can save the .trn files every particular timesteps or iterations etc. Something similar to that )

Are you looking for entire fields? Or just the pressure drop across your domain and velocity at a point or along a line?

Have you taken a look at the post processing tutorials yet?

I havent looked at the postprocessing tutorials. Could you point out which one are those ? And I basically want to see the entire field and macroscopic and microscopic variables during the transient run. And mainly in CFX you can save every 1000 or 10000 iterations result when doing the transient run. Here I havent seen something similar to that.

The introduction tutorials should give you a decent idea on how to do what you're looking to do. The others you may want is to look at having it output internal tables at the iteration frequency you're looking for.

If you specifically want to write out .trn-files you can easily do that via File/auto-export and specify the interval, the variables and the domain you want to.
