LiveLink™ for Revit®


Bring the Power of Multiphysics Simulation to Architectural Projects

LiveLink™ for Revit® provides an integration tool and interface for transferring geometry of elements from your architectural design projects in Autodesk® Revit® software to COMSOL Multiphysics® software.

Autodesk® Revit® is a leading software for architectural design that supports CAD design and Building Information Modeling (BIM) workflows. Through the LiveLink™ interface, you can generate the geometry for selected rooms and included architectural elements in a building. The selected rooms and elements are synchronized to the COMSOL Multiphysics model, where you can include any physical effects for an accurate simulation.

Efficient Model Set-up

For an efficient model set-up, LiveLink™ for Revit® generates selections for the various elements. When applying modeling conditions or functionality to a specific element, you can simply select it by name via the interface. The selections also ensure that when changing your Autodesk® Revit® design, e.g. moving a wall, you will retain all of the settings on model domains and boundaries in COMSOL Multiphysics®.

Product Features

Product Features

  • A LiveLink™ interface that synchronizes between the Revit® 2016 or 2017 versions of the software and COMSOL Multiphysics®when both are running simultaneously
  • Geometric object for room volume is automatically created during synchronization
  • Synchronize 3D architectural elements (solids and surfaces) between Revit® geometries and COMSOL Multiphysics®
  • Synchronization of conceptual masses and mass parameters that allows for the optimization of conceptual shapes and forms in the Revit® project from the COMSOL Multiphysics® model.
  • The synchronized geometry is associative, i.e., the architectural model can be modified in Revit® without the need to re-apply model settings in COMSOL Multiphysics after re-synchronization
  • Synchronize selections of architectural elements between the Revit® project and the COMSOL model
  • Connect to COMSOL Server™ from within Revit® to browse and run apps from within the Revit® interface, including those that use geometry synchronized with Revit®.
  • File import of the most popular CAD file formats, see table below
  • Encapsulate geometries to model phenomena in the surrounding domains
  • Export geometry files to the Parasolid® and ACIS® file formats
  • Geometry repair through identification of geometric inconsistencies and knitting surfaces to create solids
  • Defeaturing through the finding and deletion of fillets, short edges, sliver faces, small faces, and spikes
  • Manually deleting faces and healing the resulting gaps through filling (creating a new face) or patching (shrinking or expanding adjacent faces)
  • Detaching faces from a solid object to create a new solid object
  • Cap holes or empty spaces to fill the space and create modeling domains
  • Patch removed faces by growing or shrinking the surrounding surfaces to cover the removed face
