Version 11.0w

• Direct input of a DXF file in BISCO (without preparation in BiscoDxf).
  The bitmap is automatically created using the (default) layer definitions.
• A layer name in a DXF file starting with a number of 3 digits (000 up to 255) sets this number as colour number of the layer (also in BiscoDxf).
  A layer name of format “xxx_y_name” sets the colour number (3 digits xxx) and fill type (digit y, from 0 up to 3).
• New parameter “Use border colours” in function Bitmap > Size…
• Improved detection of grooves and interconnections in function Bitmap > Split Zones…
• Faster triangulation of bitmap (as initial step of thermal system calculation), because of elimination of graphic feedback.
• The radiation simulation in a TRANSMAT cavity at the bitmap border is improved.
• Graphic output of single isothermal line.
• Batch calculation starting from DXF files with included EN 10077 preparation.
• Creation of graphic report files also possible in batch calculation (from either BSC or DXF files).
• Show left top point coordinates of current colour from Measures window in status bar (to facilitate its location in the bitmap).
• New tool BiscoBmp to edit and prepare BMP files (containing move/copy of selection within bitmap).
• Multiple BISCO simulation results can be imported in one step in the Word report template.
• Word report template with improved style control of imported report items.

Version 10.0w

• Automatic preparation of the bitmap to minimise the user intervention for the calculation of the thermal transmittance of a window frame according to EN ISO 10077.
• New rules for type EQUIMAT (rules CEN_DIR_I and CEN_DIR_E), TRANSMAT (rule CEN_DIR_I) and BC_FREE (rule CEN_DIR_I) to calculate the thermal conductivity and convective heat transfer coefficient from the real heat flow direction.
  These extensions are in line with the standard EN ISO 10077-2:2017.
  The RADCON module needs to be installed to use these new rules.
• Distances and U values can be defined in a slanted direction (using Distances window).
  The Derived Thermal Properties dialog box is adapted to include possible references to those (slanted) distances and U values.
• Current split zone parameters can be set as default parameters (saved in the BISCO parameter file).
• Batch calculation and command line program execution with automatic report text and report index files generation.

  Bitmaps of up to 32767 x 32767 pixels are possible.
  The maximum number of nodes depends on the RAM installed.
