Request a demonstration version of Solaria The demo is actually the latest release of Solaria. Without a license, it comes up in demo mode. The only limitation is you can't solve or save models with greater than 1000 nodes. There is a folder called 1000Nodes that contains many example models having less than 1000 nodes along with a description pdf. If you have any questions, please don't hesitate to contact us.
If you would like a fully functional 30 day trial just let us know.
