I have a question regarding the energy simulation. When I try to simulate an umi file I get the 

umi energy error: Could not find file 'C:\Umi\Temp\umi-shoeboxer\sønderborg_v1\sønderborg_v1.dat'.

A few days earlier I simulated the energy without problem. Do you know what is the problem?

Thank you in advance,

It's very strange that it would suddenly stop working. Often times, the last error you see in the Rhino console is not the first error - can you scroll up in the console output and see if there are any other error messages?

I created another file in rhino and I reassigned the template to the buildings and now I don't get the error anymore. I used the rhino file from another computer through dropbox, so there is a small possibility to have compatibility problem or there were some files missing but I am not sure. Thank you.

In Short

Umi is a Rhino-based design environment for architects and urban planners interested in modeling the environmental performance of neighborhoods and cities with respect to operational and embodied energy use, walkability and daylighting potential. Since 2012, Umi has been  developed by the Sustainable Design Lab at the Massachusetts Institute of Technology with support from a National Science Foundation EFRI_SEED project, the MIT Energy Initiative, the Kuwait-MIT Center, the Center for Complex Engineering Systems (CCES) at KACST and MIT, Transsolar Climate Engineering and United Technologies Corporation. Further tool developed is now also being conducted at the Environmental Systems Lab at Cornell University.

A first public version of Umi was released during a public symposium on Sustainable Urban Design on May 6th 2013 at the Massachusetts Institute of Technology. Version 2.0, which also includes an embodied energy module, was released on November 7th 2014.
