flixo functionality

The program is divided into a modeling and a computation/evaluation section. Whereas the modeling section defines the physical situation (geometry, boundary conditions,materials), in the evaluation section the results are quantified and presented graphically. Due to the well-proven and time-saving template model, individualized results reports are produced automatically and are dynamically updated during a renewed computation.

Inputs

The integrated and expandable component library of flixo enables components to be simply transferred using the mouse (drag & drop) into the current design.
Layers: Objects can be arranged on various layers and the layers can be selectively superimposed, masked out, printed and frozen.
Snapping aids: Objects can be aligned with various auxiliary objects such as auxiliary lines, grids and special points on adjacent objects.
Associative elements such as local results and isothermals.
Mouse and keyboard-controlled input.
Geometrical operations such as grouping, merging, cutting, differences between objects.

Material data base with more than 1000 materials from various standards (EN ISO 12524, EN ISO 10077-2, EN ISO 673, EN 6946, DIN 4108-4)

Results

Isothermals and false-color images of any building detail for qualitative thermal assessment and optimization.
Temperatures at freely determined design points.
Heat flux density at freely determined design points.
Minimum and maximum surface temperatures at freely determined design boundaries and critical room humidities for the assessment of possible mildew formation and condensation problems.
Heat flow at freely determined boundary lines.
Thermal transmission coefficient (“k value”) and length-related thermal transmission coefficient (“psi value”) for the quantification of the thermal bridging effect.
Automatic computation of framework k values

Features

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.

flixo is optimally integrated into the Windows 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.
