U-Value

[petercat]

I’m simulating a window. How can I calculate an overall U-factor? Does E2D provide a convenient way to integrate the heat flux along a path, or must it be estimated manually?

I was able to estimate the overall U-Value manually by subdividing the glazing plane into imaginary zones, placing a heat flux sensor in each zone, and using a spreadsheet to add the product of zone area times zone heat flux. It’s crude, but gives reasonable answers, particlarly when studying the relative impact of geometry or material changes.
