Dialog: Quick Graph

DialogSchnellgrafikA 3.gif

After the calculation you can access the quick graphs through the project explorer. These graphs give you a quick overview of the calculation results (as an alternative, the result graphs have nicer formatting and numerous configuration options, but they are slower).

You can pan a quick graph with the right mouse button held down.

You can zoom into a quick graph by dragging open a zoom frame from upper left to lower right at the desired location. You can zoom out by dragging open a zoom frame from lower right to upper left.
 

The right mouse button opens a pop-up menu:

DialogSchnellgrafikPopUp E 0.gif

"Zoom back":
Zoom out to the graph's original size.

"Print...":
Print the graph.

"Export":
Export the graph to an ASCII file or as a picture in bitmap or metafile format.
Version notice: these export options are only available in WUFI Pro.
 

A specialty of the quick graphs are two graphs plotting the surface temperatures of each time step against the corresponding relative humidities:

DialogSchnellgrafikB 2.gif

Each point in this graph represents the hygrothermal conditions at the left or right surface of the component at a certain time.

The graph also shows the limiting isopleths for building materials, LIM B I and LIM B II, below which no mould growth is usually to be expected [1]. If the conditions lie above the limiting isopleths for a longer period of time, mould growth may be possible, but additional criteria are needed for a firm assessment. In particular, this applies to the exterior surface where environmental conditions may very efficiently prevent mould growth (killing mould through high temperatures or UV exposure, washing spores off through rain etc.), although it would be possible according to the simple isopleth model.

This graph therefore allows a quick assessment whether mould growth is unlikely (conditions always below the corresponding LIM), or whether more detailed investigations are needed for a definitive evaluation (conditions above the corresponding LIM for longer periods of time).

LIM B I: bio-utilizable substrate, e.g. wall paper, plaster board; products made from easily degradable material, material for permanently elastic joints, etc.
LIM B II: substrates with porous structure, e.g. plasters, mineral building materials, some woods, insulating materials not belonging to group I, etc. If strongly contaminated, these materials belong to group I.
