SOLIDO
Efficient method to calculate 3D steady state heat transfer in objects of any shape
Features
 Steadystate thermal simulation of all shapes in 3D
 Compatible with STL files
 Minimal simulation time due to powerful finite element solver
 Superior graphic representation of isotherms and isofluxes
Application fields
 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 100772)
 Heat transfer via the ground (ISO 13370)
 Heat transfer in masonry and masonry products (EN ISO 1745)
Input and geometric modelling
 Object modelled with blocks
 Free independent positions of the eight vertices of a block, allowing shapes as prism, pyramid, parallelepiped, etc.
 Corners around vertices can be rounded to form solids with quadratic surfaces: sphere, cylinder, cone, etc.
 SOLIDO blocks can also refer to STL files as exported from CAD systems (e.g. AutoCAD)
 The point coordinates of a STL file can be transformed in SOLIDO to adjust its position
Thermal properties and boundary conditions
 Thermal properties linked to colours of blocks
 Material properties with extensive material database
 Boundary conditions at material surfaces, material interfaces, inside materials (volumetric heat source)
 Improved simulation of separated radiation (using view factors) and convection (function of difference between local surface temperature and air temperature) by use of RADCON module
 Automatic calculation of thermal properties for air cavities in accordance with international standards
Mesh generation
 SOLIDO uses a rectangular mesh with node fitting to the true object geometry

The user defines a 3D rectangular grid (comparable to grid in TRISCO). The grid can be equidistant based on a given resolution and then be optimised to minimise the number of nodes
 The object is rasterised in relation to the calculation grid to obtain a rectangular approximation

The node coordinates at the outside surfaces or in the interfaces between different colour regions are fitted unto the original object surfaces, to achieve a close match to the original geometry
Output
 Superior graphic representation of isotherms and isofluxes
 Text output of temperatures and heat flows
 Investigation of surface condensation
 Calculation of thermal transmittances and thermal bridge properties
Compatibility with other Physibel tools
 SOLIDO can read TRISCO data
 SOLIDO can read BISCO data (creates STL files per colour for extruded profile, based on triangulation mesh)
