Hi TP,
following the topic in the User Guide I mentioned earlier, you can just record the execution of several macros into one. Just start Macro Recording and then in the Macro Execution Control select one macro after the other and click Record Only for each of them in the order you want to run them. Afterwards, end macro recording. Finally, you can run the new macro which then executes all the other macros automatically.
If you just want to run the same permeability simulation on different structures, it would be more elegant to just use one macro and the Python code shown in the tutorial I linked you in my earlier post. There, different structures are saved in one folder and the goal is to analyze Open and Closed Porosity on each of them automatically. You only have to replace the command for the open and closed porosity by the corresponding permeability simulation command.
Best regards,
Janine
