Flixo is optimally integrated into the Windows XP/2000/NT environment and makes use of the familiar methods:

• Cut/Paste and Insert as well as Undo/Restore of the last actions.
• Different flixo documents can be edited in parallel.
• Interchange of flixo data (design details, results) via the clipboard or using drag & drop. For example, results can be integrated directly in a Word document or copied or moved from one design to another.

The mathematical core of flixo:

• Computation of temperatures according to the finite element method (triangular elements); iterative solution of the arising system of linear equations using an optimized, conjugated gradient technique.
• Automatic grid pitch reduction at critical points.
• Computation of equivalent thermal conduction coefficients for air cavities and automatic subdivision of air cavities according to EN ISO 10077-2.
• Unrestricted number of nodal temperatures (depending on the hardware used).
• Consideration of materials with orthotropic material properties.
