Version 7.1 update

2009-03-30:

· Fixed error message ”HEAT2 is registered but ActiveX does not exists". This alert came in some cases for a user without admin rights running HEAT2 under Vista and XP.

· Calculation of psi-factors: HEAT2 assumed for some cases that the indoor climate were placed on the left side of a wall/roof leading to that legends for external/internal lengths ”L(i)” and “L(e)” sometimes were switched.

· Frame cavities: calculations for frame cavities gave an overestimation of a few percent for the heat flow due to radiation when the cavity was enclosed by surfaces with temperatures below zero.

· Recorder: fixed label “Q, point (x,Y) [W/m?]” => “Q, point (x,Y) [W/m²]”.

· System info: “Available virtual memory” was negative if RAM size was above 2 GB.

· Options for steady-state: options for optimization of over-relaxation and numerical scheme are now saved to file.

· Function steps editor: “Paste from clipboard” added to menu.
