Dear Jesus,
In the window that says "simulating flux maps," click Close when the simulation ends, and then go to the folder that you chose to save the LK script. The process should work like this:
1. Start SAM and open or create the file for the power tower system.
2. Click Shift-F5.
3. Choose a folder to save the .lk file for the tower model.
4. When the flux map simulation finishes, click Close in the Simulation window.
5. Choose a folder to save the .lk file for the financial model.
6. Go to the folder you chose in Step 1 to find the .lk file for the tower model.
In the next version of SAM, the folder containing the .lk files will automatically open.
Best regards,
Paul.
