Monitoring Surface Temperature and Heat Flux in WUFI® 2D and Exporting Results

[Mir_Hedayat]

Dear WUFI Support Team,

I hope you're doing well. I am currently working on a research project using WUFI® 2D and have some questions regarding the monitoring and export of simulation data.

I would like to monitor the temperature on the interior surface of a multilayer wall assembly over time, and also determine the heat flux through specific parts of the assembly during the simulation. My goals are:

To track surface temperature continuously over the simulation period.

To measure the heat flux between two specific points (e.g., across a layer or between layers) in the 2D wall assembly.

To export numerical data from the simulation results (e.g., temperature, heat flux) for further analysis in a spreadsheet (Excel or similar).

However, I have encountered some limitations:

I cannot find a way to predefine monitoring sections or points (like a line or surface) in WUFI® 2D before running the simulation.

After the simulation, although I can view graphs, there does not seem to be a straightforward way to extract the raw numerical values from these graphs (e.g., temperature or heat flux values over time).

I would like to analyze these values outside of WUFI (e.g., in Excel), but I am unsure how to do that.

Could you please advise on how to:

Monitor and record temperature on a specific surface (e.g., the interior face of the wall)?

Select two points to evaluate heat flux through a layer or between layers? Right now when I choose one ponit I am unabale to select the second point, no matter where I click on my assembly.

Export result data (temperature and heat flux) in a usable format?

Any tips, documentation, or guidance you can provide would be greatly appreciated.

Thank you in advance for your support.

Best regards,

Dear Mir Hedayat Moosavi,

it is not possible to monitor the temperatures during the simulation. Afterwords you can display and export the data using WUFI Graph. For 2D there is also the possibility to set up templates which allows to do the same evaluation for several calculations with different materials, boundary conditions etx. (Please note: The grid must not change).

For the fluxes you have to pick the second point in the same row or column of grid elements like the first one.
Use right click in selection mode for fluxes to "Show catching points"

There is a help for WUFI Graph usually here:

Code: Select all

c:\Program Files (x86)\WUFI\Tools\WUFIGraph\help\WUFIGraph_en.pdf

The result file (*.wfd) is in hdf5 format since WUFI 2D 4. From this one you can extract the raw data with suitable tools.
