PRESENTATION BISCO V12

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.
Presentation BISCO v11

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.
  • 64-bit option:
    With the 64-bit option the 2 Gbyte RAM limit of the standard 32-bit BISCO version can be exceeded.
    Bitmaps of up to 32767 x 32767 pixels are possible.
    The maximum number of nodes depends on the RAM installed.

    • Resize pixel without modifying the bitmap size (e.g. to get a rounded pixel size)
