How to compare results from different runs in SimScale ?

 The "Compare" function (red frame) in SimScale is a post-processing tool used to analyze and visualize the results of multiple simulation runs. It allows you to see the differences between these simulations side-by-side, helping you understand how changes in simulation parameters or geometry affect the outcome.

Here's a breakdown of how the Compare function works:

1. Selecting Simulations: You choose two or more simulation runs that you want to compare.

2. Visualization: SimScale presents the data from the chosen simulations in a synchronized way. This means that if you rotate the view in one result, the view in the other results will also rotate accordingly. This allows for a more direct comparison of the data.

3. Data Types: The Compare function can handle various data types typically found in engineering simulations, such as:

   • Stress
   • Strain
   • Displacement
   • Temperature
   • Other relevant data sets depending on the simulation type

4. Highlighting Differences: SimScale can calculate the absolute or relative differences between the corresponding data points from the compared simulations. These differences are then visualized using color gradients or other visual cues, making it easier to identify regions where the variations are the most significant.

By using the Compare function, you can gain valuable insights into how design changes or material choices impact the performance of a system. This can significantly improve your design iteration process and help you optimize your engineering decisions.

Here are some additional points to consider:

• The Compare function is a visual tool and cannot be directly accessed through programming code like Python.
• SimScale offers other post-processing features that can complement the Compare function, such as plotting and data extraction tools.

I hope this explanation clarifies the functionality of the Compare function in SimScale.
