VOLTRA Features

Features

  • Transient thermal simulation of 3D rectangular shapes
  • Geometrical input is same as in TRISCO
  • Temperature dependent material properties
  • Detailed solar processor
  • Graphic animations (AVI files) of time varying temperatures
VOLTRA Applications

Applications

  • Transient analysis of thermal bridges
  • Dynamic thermal analysis of floor heating
  • Analysis of building elements exposed to fire (Eurocodes)
  • Floor heating (EN ISO 11855-2)
  • Ground heat losses (EN ISO 13370)
  • Heat exchange problems (mass flows)
  • Advanced façade engineering
  • Passive solar building design
  • Calculation of solar heat gains

 

VOLTRA Input and geometric modelling

Input and geometric modelling

  • Same as in TRISCO
  • Additional input of material densities, specific heat values, solar reflection factors, solar transmission factors
  • Thermal conductivities and specific heat values may be temperature dependent (e.g. useful in fire simulations)
  • Solar reflection factor may be function of angle of incidence

 

VOLTRA Dynamic boundary conditions

Dynamic boundary conditions

  • Boundary conditions are time dependent functions: constant, steps, periodic, climate values, fire curve, ...
  • Solar zone with 3D solar processor (any geographical location, based on climate files with global and diffuse solar radiation)
  • Ventilation flow functions
  • Improved simulation of radiation and convection by use of RADCON module

 

VOLTRA Output

Output

  • Graphic animations (AVI files) of 3D views or 2D cross sections of time varying shadows, absorbed solar radiation, temperatures, heat fluxes
  • Snapshots at any time step
  • Tables and graphs of time varying solar fluxes, temperatures in given nodes, heat flows through given faces

 

VOLTRA Compatibility with other Physibel tools

Compatibility with other Physibel tools

  • VOLTRA can read TRISCO data
  • Same function definitions as in CAPSOL
