Linear Fresnel VBA code generation not working

Hi,

I am trying to run an linear fresnel simulation case using the Excell/VBA code generation tool of SAM. I have put the samsim.dll file inside the folder containing the .vba and .dat files. However, whenever I try to run the code I get a message that samsim.dll cannot be found. I generated a phyton code and this one indeed worked (by putting msvcp100.dll, msvcr100.dll and ssc32.dll files in the same folder as suggested in the manual). Any idea why the vba code does not work? I am using the latest version of SAM (2011.12.2) and x64-bit machine running Windows 7.
Thank you,
Luis Dominguez

Luis,
I'm having the same problem. Were you ever able to figure out a solution?

Hi Reeves,

Unfortunately, I haven't been been able to figure out a fix... yet...

Hi Luis,
although the last forum entry is quite old, I am curious whether you could fix the problem. It seems that I have the same issue now:
I am used to work with SAM for a long time (since 2010), using VBA code. The code was running 2 years ago. Now I try to install everything on a new computer with new operation system (Windows 10, x64 based processor), and it seems that my old "samsim.dll" version from 2011 is not compatible anymore. I receive the same message you mention above ("samsim.dll cannot be found"), although it is saved in the correct folder.
Any idea how to solve this? Is there a new version von samsim.dll available?

Thanks,
Klaus

Hi Klaus,

The old samsim.dll worked with 32-bit versions of Windows, so is likely not compatible with Windows 10 x64.

The current version of SAM is SAM 2021.12.02, and it uses the ssc.dll library. The easiest way to get a copy of the library is to download and install SAM: sam.nrel.gov/download .

See the "The SSC Library" section of the SAM Software Development Kit (SDK) page for help locating the library file: sam.nrel.gov/software-development-kit-sdk
 
Best regards,

Hi Paul,
thank you for the quick replay. I have replaced the old samsim.dll with the new ssc.dll from the current verion, and adapted the VBA code accordingly. The ssc.dll ist found now, but the called function is not found in ssc.dll.
My idea is to replace the new ssc.dll (from SAM 2021.12.02) with an older version (either samsim.dll or ssc.dll) that was released between my original version (SAM 2011.11.29) and the 2021 version. Could this work? Would you have a recommandation which version is the most suitable one?

Thanks,
Klaus
