Dear Charles,
There is a bug in SAM 2017.1.17 that prevents simulations from running when you use the optimization check boxes on the Heliostat Field page. It works fine when you click the "generate heliostat layout" and "optimize solar field geometry" buttons, but not the check boxes.
We will fix that in the next update. In the meantime, you can fix the problem as follows:
UPDATE 3/1/2017: THIS WORKAROUND SOLUTION DOES NOT WORK. WE WILL RELEASE A SOFTWARE UPDATE SOON.
- Download the Tower Solar Field.ui file from here (UI 360 KB).
- If SAM is running, close it.
- In the c:/SAM/2017.1.17/runtime/ui folder (see
here
to find the file in OS X), find the Tower Solar Field.ui file, and rename it to Tower Solar Field OLD.ui.
- Save the Tower Solar Field.ui file you downloaded in Step 1 to the c:/SAM/2017.1.17/runtime/ui folder.
- Start SAM and test your parametric runs.
Please let me know if that seems to solve the problem.
Best regards,
Paul.
