Torch 3D

TORCH 3D is ESR Technology’s impacted and shielded jet fire consequence model. The software allows users to model the effects of a jet fire within a 3D geometry without the long runtimes of full CFD calculations. The flame shape is adjusted for large obstructions such as firewalls and plated decks and thermal radiation calculations automatically take account of the shielding effects of the imported geometry. TORCH 3D is designed to be easy to use with intuitive results available in a matter of minutes.


Capabilities include:

  • See the effect of input changes on flame shape and orientation in real time
  • 3D view of flame shape and thermal flux levels
  • Quickly compare shielded and unshielded thermal flux results
  • Get results for points, transects, 2D Slices or in full 3D
  • Export images and tabular results easily into your reports
  • Import your existing 3D geometry files
