Simcenter STAR-CCM+ provides two possibilities to create a video of a transient simulation result. Users can create a video directly in Simcenter STAR-CCM+ using a Solution History file (.simh) and a Recorded Solution View. The alternative way is creating and saving images from a scene using the "Update" feature and creating videos with external media programs.


This KB article illustrates how to create videos from transient simulation results in Simcenter STAR-CCM+. There are two ways to do this, which are shown below:

1. Create a Solution History file (.simh)
The following steps are necessary:
  • Set up a Solution History File
- Right-click the Solution Histories node and select New.
- In the opened window, choose a name for the simh file and click Save. Under Solution Histories node, a new node with the specified simh file name will be created.
- In the Properties Window of the created Solution History, select the function and the input boundaries that should be saved. 
- Click the Updates node and specify the Trigger and Frequency.

- Run the simulation.
  • Create a Recorded Solution View
- Right-click the saved Solution History and select Create Recorded Solution View.
- A new node is created under Solution Views.
  •   Create an Animation from the Solution View
- Under Solution Views > simh file > Animation right-click and select Edit.
- In the opened window, select an Animation Mode and set up the Solution Time Animation. Close the window.
- You can go to the created Scalar Scene you would like to use for the video. Right-Click in the Graphic Window, go to Apply Representation to Displayers and select the created Solution View

- Hit the animation Record button in the toolbar. 
- Choose the movie format and a file name and click Save. The movie will be now exported and saved in the target location.

2. Save images of a scene and create a video with your media program of choice

- Go to the Scenes node and expand the scene you want to use for video creation.
- Expand the Attributes node. 
- Click the Update node and change the settings in the Properties Window. Select a File Format for the images, a Trigger, an Output Directory, and choose a Base Filename. It is also important to activate Save To File.
- Specify a Frequency for the selected Trigger.
- Run the simulation. After each update of the scene, an image file will be saved. With these files, it is possible to create a video using an external program.
