Error 404: Cannot find definition

Hi,
I downloaded latest SAM version and tried to compile Fortran code files from the directory C:\SAM\2013.9.20\exelib\trnsys\source for CSP tower system model and keep getting these errors...

"Error 404 - Cannot find definition for MODULE TRNSYSCONSTANTS"

For SAM Weather Type 15, Type 221, Type 806, Type 224, Type 223, Type 222...

Can you please help?

Dear Brian,

We include the FORTRAN source code files in the SAM distribution for the CSP model components as a reference for people who want to understand how the models work, not as a resource for building your own models in FORTRAN. We do not provide technical support for that purpose. The FORTRAN files were developed to work with the TRNSYS simulation platform, so they do not contain all of the modeling components required run simulations.

You can build your own system models using SAM components using the SAM Software Development Kit (SDK). However, the CSP models are not yet available in the SDK -- they should be available with the next release of SAM in 2014.

UPDATE: The CSP models are part of the SDK as of January 21, 2014. See https://sam.nrel.gov/node/68918.

 

Best regards,
Paul.

Dear Brian,

It turns out that the FORTRAN files that we included with SAM 2013.9.20 are not up to date. You can download the current file collection here: https://sam.nrel.gov/webfm_send/448 (ZIP 530 KB).

Best regards,
Paul.
