Hello everyone,
There are a couple of questions here, and I'll try to address them in order.
1. To reiterate Paul's earlier response, some of the intermediate files are available after executing a SAM run by pressing Shift+F9 while in SAM. This opens a temporary working folder which should contain a folder with the same name as your SAM project name. Open this folder, then the "BASE" folder, and you'll find the intermediate files. Not all of the input and output used by DELSOL is available here, so I've created a copy of PTGen (the program that executes and processes data for DELSOL) that optionally saves all of the DELSOL output.
We'll follow up shortly with instructions on how to get a copy of this version of PTGen.
Follow these steps to view all of the DELSOL3 output that SAM uses: [update 7/7/2014: Please use the steps below for SAM 2014.1.14 instead of these steps to generate the DELSOL3 output files.]
1) Run a simulation in SAM normally.
2) Navigate to the temporary working directory (as described above).
3) Copy the PTGen executable into the working directory.
4) Open the file "SAM_Tower_DELSOL.inc" with a text editor, and add a line after the "Rec_d_spec" variable at the end (and before the "/") that reads exactly "save_files = 1."
5) Run PTGen.exe by double clicking This will re-run PTGen normally, but will save the output from all of the DELSOL runs.
You should see a single file with information from the solar azimuth/elevation parametric run (DELSOL3_eff_mat.txt), and a series of files with receiver flux map information (DELSOL3_Flux__.txt). You will also see the consolidated data that the SAM hourly simulation tool uses with the "array_view.csv" and "fluxmap.csv" files.
2. Since NREL does not own DELSOL, we aren't at liberty to distribute it at this time. The code was originally developed by Sandia National Lab. 3. DELSOL is not well-suited for modeling heliostats by user-specified coordinates. Although this option is available, I would recommend not using DELSOL for this purpose without some other type of validation. The more correct use of DELSOL with user-specified fields would be to convert your design into the "heliostats per zone" table format on the Heliostat Page and running the simulation that way. DELSOL uses analytical approximations that are much different than modeling each heliostat individually, so the program regularly fails with user-specified coordinates.
Thanks,
