Plus:DefiningTheComponentAndTheNumericalGrid

When the building is defined with the building wizard or by script file the next step is to define the assembly of the components in detail and subdivide them into small numerical grid elements.

The definition of the assembly and the individual layers is done interactively with a graphical diagram of the assembly.

Either you take one of the already given assemblies in the database for the components or you define a new one by copying and modifying an existing assembly or configure a new assembly by using the materials in the material database.

WUFI^®plus comes complete with databases which offer a selection of assemblies, materials and window glazing. (Please note, however, that due to large variations in the materials and often incomplete or inconsistent literature data, the data provided here should not be taken as divine revelations. They are just intended to give you a starting point.) You can supplement the databases with your own assemblies, materials or windows.

The transport equations cannot be solved analytically. To allow a numerical treatment, the components must be divided into discrete grid elements. WUFI^®plus can generate automatically a general-purpose grid which will suffice for most cases (you can select one of the degrees of fineness for the grid). For each assembly you can select the subdivision of the grid.
