Thermal Simulation Software (Flixo vs Therm)

Click For Summary
SUMMARY

The discussion centers on the discrepancies in U-Value calculations between thermal simulation software Flixo and Therm. The user, Goce, identifies that Therm may not account for heat flux in its U-Value calculations, leading to differing results compared to Flixo. Despite not considering heat flux in Flixo, the values still differ, indicating a fundamental difference in how each software processes thermal data. Goce seeks assistance from experienced users to clarify these differences and to understand how to calculate thermal bridges at corners using Flixo.

PREREQUISITES
  • Understanding of U-Value calculations in thermal simulation.
  • Familiarity with thermal simulation software, specifically Flixo and Therm.
  • Knowledge of heat flux and its impact on thermal performance.
  • Basic concepts of thermal bridging in building physics.
NEXT STEPS
  • Research the specific algorithms used by Flixo for U-Value calculations.
  • Investigate how Therm handles heat flux in its calculations.
  • Learn about thermal bridge calculations in Flixo, particularly at corners.
  • Explore case studies comparing Flixo and Therm results for similar scenarios.
USEFUL FOR

Architects, building engineers, and thermal performance analysts looking to optimize thermal simulations and understand discrepancies in software outputs.

Hey All,

Have any of you ever worked with thermal software such as Flixo and Therm? I'm having a problem with U-Value calculations differing between the two programs, and I would really liek to get to the bottom of why.

What I'm thinking:

I am coming up with some ideas based on some vague information from both parties (flixo and therm). It is looking like therm does not take heat flux into account when it calculates the U-Value through a section of a cross section. However, even when I do not consider heat flux in Flixo...they still arrive at different values.

Im hoping someone has experience with these programs! Please help!

Thank you

Is there anyone who can show me how to calculate thermal bridge at the corners - FLIXo?
Best regards
Goce
