Glad to hear it!

For future versions we are looking into ways to further reduce the amount of temporary data stored to file in cases like yours, where one is only interested in a small subset of the data.

You can remove result files from disk using the command below. Note these things however:

• When you run it, it will delete all result files from all simulations you have run up to this point

• You should read in the data you need before deleting files, for example like this:

  myVariables = mySimulationResult[{"var1", "var2", ...}]
  

• Assume all WSMSimulationData result objects that were created before deleting, will be completely unusable after deleting

Here is the command to delete all temporary result files from WSMLink:

WSMLink`Library`ClearTemporaryFiles[-1]

This command is not documented, so may change or disappear in future versions.

As an alternative, if you have control over the models, you can try to move as many variables as possible into protected sections in the Modelica code. Protected variables are not saved to the result by default (version 4.2 and newer).
