3D steady state heat transfer
rectangular blocks

Home Products TRISCO examples

The fastest most complete digital instrument for thermal analysis of current building components.
More than 25 years in the front line of thermal simulation.

Latest version : TRISCO v14.0w

  • Object modelled with rectangular blocks
  • By superposition in space a minimum number of blocks is required
  • Object parts can be copied, transformed, repeated
  • Input possible of 2D AutoCAD drawing via DXF file.
  • Material properties (thermal conductivity, surface emissivity) are linked to colours
  • Automatic calculation of equivalent thermal conductivity for air cavities modelled as materials
  Boundary conditions
  • Surface boundary conditions (to environment or between materials)
  • Volume boundary conditions (material with fixed temperature or heat power density)
  • Point boundary conditions (fixed temperature or power)
  RADCON module for TRISCO
  • Radiation based on view factors
  • Convection based on (calculated) convective heat transfer coefficient
  • Transparent materials for small cavities: conduction + radiation

  • Rectangular grid of system nodes through object block surfaces
  • Grid refinement functions
  • Extreme fast and stable solution through iteration
  • Unlimited number of nodes proportional to installed memory
  • Non-linear problems solved through iteration cycles

  • Superior graphic representation of isotherms and isofluxes
  • Text output of temperatures and heat flows
  • Calculation of thermal transmittances and thermal bridge properties
  • Thermal bridge analysis: heat loss calculation, surface condensation (ISO/FDIS 10211)
  • Thermal transmittances of building components and elements (EN ISO 6946)
  • Thermal performance of windows, doors and shutters (EN ISO 10077-2)
