I've created and LTI rom through the tutorial : Getting started with Icepak- LTI ROM. 

But the system includes non-time invariant components and I would like to visualize the temperature field within the device. I read something about the Singlue Value Decomposition Reduced Order Modelling. The Idea is to use the Lti model obtained from icepack and convert it to the SVD using it in Fluent. Can u help me. Any tutorial, ora example? I hope I have explained the problem well.
