What is Numfem Therm ?
Numfem Therm is a BIM thermal bridge analysis software in accordance with ISO 10211.
It is the first software that leverages native BIM datas to perform calculations, from localized thermal bridges to large building areas.
Fully connected with Autodesk® Revit® (2020+).
« One click » analysis, Sheets & Schedules reports, …
Powerfull finite element solver with the latest scientific improvements : adaptative mesh refinement, parallel computation, …
Full compliancy with international standards for thermal bridge simulation (10211, 10077-2, …)
Numfem Therm is a very easy using software if you are already a Revit user !
Numfem Therm is fully connected to Autodesk Revit, that means that all analysis options are linkable to Revit parameters. This system leads to a powerfull & customizable workflow : no extra option file, everything is in Revit.
Moreover, options can be imported from a Revit template or project file (a sample template file is provided during installation, but it’s very easy to make one that best suits your specific needs).
To perform a full FEM analysis, all you need is to define a callout (plan, section, rectangular, polygonal, rotated, …) where you want the analysis to take place, nothing else !
Numfem Therm automatically uses all available informations from BIM datas : objects geometry & materials, spaces, prescribed room temperature, …
Optionally, you can define dimensions to allow Numfem Therm to automatically perform psi-values calculations.
Numfem Therm contains a « state of the art » finite element solver which allows to perform a thermal simulation / psi-values calculation within a couple of seconds, even on large models.
Generating reports & sheets into Revit is very easy thanks to data injection.
Numfem Therm can save its results inside Revit, by injecting images and values into defined parameters. You can then create sheets and link to these parameters to produce high quality reports.

one of the best all-in-one Revit Addin!
Numfem Therm is a thermal simulation software, that is directly synchronized with BIM data to simulate the thermal behavior, from a simple thermal bridge to a whole 2D view.
Numfem Therm is not a 2D/3D drawing software, because it’s linked to Revit and uses its drawing capacities.
For all people involved in building energy saving : architects, thermal engineers, constructors…
Numfem Therm is the only and fully connected BIM software for thermal building simulation. It means that you don’t have to export, then re-sketch / heal / modify geometry, assign materials, temperatures … Numfem Therm does it all automatically ! It saves a lot of time, and even permit almost automatic iterative analysis.
Moreover Numfem Therm use a very fast and powerfull finite element solver based on the latest mathematical improvements such as high order finite element, adaptive mesh refinement, multithreaded linear solver…
If you are already BIM convinced, Numfem Therm is up to perform a psi value calcultion in few seconds compared to a « traditional » approach which takes several minutes : sketch+assignment+calculations !
Numfem Therm works with Revit 2020 and 2021, under windows operating system with no minimal requirements others than Revit’s ones.
Numfem Therm only support native windows operating system (virtual machines may be supported, but haven’t been tested).
Currently Numfem Therm is free to use until the 31th of December 2020.
Numfem Therm contains everything in one software, no additional module.
Prices will be released very soon.
Numfem Therm will be available as an annual subscription, with several types of licenses (standalone, cloud floating, educational, server …)
At this moment we do not provide training, but we plan to do so in the future.
If you have specific needs in this domain, feel free to contact us.
Contact us through the contact form, we’re open to discussion.
We already support :
- ISO EN 10211 for thermal bridges : psi value, as well as the exterior value for the PHPP and the interior psi value (for the RT ex/RT 2012/RE 2020 all the french thermal regulations.
- ISO 10077-2 for thermal performance of windows : Uf and Psi edge value.
- CEN 673 for glass in buiding : Ug value.
No ! You’re free to work as you want. The connexion with Revit is mainly based on the definition of project/global/shared parameters. We provide a sample Revit template but you can automatically import the settings from one Revit project/template to an other Revit projet.
Numfem Therm is currently compatible with Autodesk Revit, but we may investigate the connection with ArchiCAD in the near future.
Unfortunately, current real world IFC files do not contain enough information to perform an efficient/reliable thermal simulation.
That being said, we are doing a permanent technological survey, and we will study OpenBIM solutions as soon as they can provide us with the same level of correctness/accuracy/reliability than direct BIM analysis.
Numfem Therm is based on a BIM paradigm, that means datas and geometries must be changes in the BIM project.
Real 3D details are sometime very complex and time consuming, that’s why Numfem Therm is compatible with 2D drawing details in Revit using filled regions in callouts. Revit is very powerfull for 2D parametric modelings, AutoCAD is not useful anymore.
Reports are made directly in Revit using sheets and result pictures created by Numfem Therm.
Yes, Numfem Therm is fully customizable as regards to :
- Language, we already support english and french. We can easily add others languages on demand.
- Unit system : SI and Imperial
- The graphical user interface uses modern windows standards, that’s mean it’s fully customizable (themes, dockable panels, layouts…)
That’s a pretty good question ! We’re thinking and investigating on that… If you have some ideas, let us known !
Revit can import these files in a 2D view, but the best choice is to create 2D generic family objects.
As far as the 2D is concerned, we plan to provide more calculations : hygrothermal simulations, solar radiation, complex ventilated models, parallelization , batching…
Expect some news in the following months … stay tuned !
We’re open to any relevant improvements, contact us in the contact form !
We’re always looking for talented profiles. Feel free to contact us !
