Using Solution Snapshots

A snapshot is essentially a copy of the selected solution data (scalars/vectors for that moment in time) in a simulation file. Snapshots can be used to compare multiple steady state solutions in a single simulation file, such as different design iterations.

To create a snapshot:

1. Right-click on the simulation history file in the object tree, and select Create Snapshot.
2. In the Create Snapshot dialog, give the snapshot a suitable name.
3. Click OK to close the dialog and add the solution data to the simulation history file.

A suggested procedure for comparing steady state simulations is as follows:

1. Create a simulation history file.
2. In the Properties window, disable the Auto-Record property so that no data is saved at each iteration.
3. Continue by selecting the scalars/vectors you want to save.
4. Set up a case and run it to convergence.
5. Create a snapshot of the solution, as described above, giving it an appropriate name.
6. Clear the solution.
7. Set up the case with the new settings you want to test.
8. Run the solver to convergence.
9. Create a snapshot of the new results.
10. Repeat steps 6 - 9 as many times as you want.
11. Apply the recorded solution view, which provides access to all the saved snapshots, to a scene and switch between the snapshots.

To perform a side-by-side comparison:

1. Create additional recorded solution views, where each solution view displays the data from different snapshots.
2. Create multiple scenes.
3. Assign a different recorded solution view to each scene.
4. Arrange the scenes side by side.
