VOLTRA
Detailed simulation of transient thermal effects 3D building elements
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
- Software operational in English, French, German and Dutch
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
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
RADCON feature for VOLTRA
- Detailed simulation of radiation based on view factors
- Extreme fast and stable calculation of non-linear radiation problems
- Convection based on (calculated) convective heat transfer coefficient
- Transparent materials for small cavities: conduction + radiation
- Validated according to EN ISO 10077-2:2017 (radiosity method)
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
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
Compatibility with other Physibel tools
- VOLTRA can read TRISCO data
- Same function definitions as in CAPSOL
