Dear everybody,

When i'm trying to derived a value, there are multiple options to choose from in the data set. Why is this so? the values derived are different between each data set. I've clear the solution before computing. thanks!

Hi,

The Solution Store items contain the results from study steps other than the last. So, it seems like you have three study steps within your study. You can actually see the Solution Store nodes in your solver sequence, as in the attached screenshot.

As an example: If you solve a stationary study steps to provide initial values for a time-dependent study step, the stationary results will be available in a Solution Store data set.

Regards,
Henrik
