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.
  • 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.

Version 9.0w

  • BiscoDxf: conversion of DXF file to BMP file
    - Bitmap size, placement and resolution can be modified at any time
    - Load layer definition file of other data
  • Read/write compressed 256-colours BMP files
  • Faster response times when using drawing tools
  • New bitmap editing functions:
    - Crop bitmap borders to remove border margin around drawing
    - Import BMP file into current bitmap
    - Delete colour preserves adjacent hard materials and expands adjacent soft materials (based on thermal conductivity)
  • View/impose U values at bitmap borders
  • Calculation of equivalent thermal conductivities of air cavities:
    - Optimisation of air cavities by detecting grooves and interconnections (smaller than 2 mm or 10 mm)
    - Editable surface emissivities
    - Automatic adjustment of heat flow direction
    - Use solution temperatures or default temperatures
    - Cavity at bitmap border mirrored or not (i.e. bitmap border is axis of symmetry or not)
  • Thermal transmittance of window frame:
    - Frame with two glazings (i.e. two insulation panels)
    - Detect zones of reduced heat transfer (at internal boundary condition)
    - Initialisation of distances (based on window frame colour number)
    - Adjustment of distances with resize of bitmap or pixel
  • Additional BISCO data template with more colour numbers for air cavities
  • Text output: relative humidity for surface condensation
  • Report generation:
    - Free definition of graphic report files (PNG or BMP)
    - Function "Make Report" generates text files and graphic files
    - MS Word template document with macro to import report files at bookmark locations
Presentation BISCO v9

Version 8.0w

  • More bitmap functions:
    - Insert/delete pixel band (e.g. to modify the width of a material layer)
    - Resize pixel without modifying the bitmap size (e.g. to get a rounded pixel size)
    - Delete colour in bitmap (e.g. to clean up the bitmap)
    - Merge colours (to reduce the number of colours having the same thermal properties)
    - Zoom in/out via mouse wheel
  • More graphic output functions:
    - Automatic labelling of colour numbers in bitmap
    - Fill heat fluxes (to show the magnitudes of the local heat flow vectors)
  • BiscoDxf: tool for fast conversion of DXF drawing (R14) to BISCO bitmap
    - Benefits: free definition of pixel size and bitmap size
    - Interesting for productive input of large amounts of well prepared DXF drawings
    - BiscoDxf only supports a limited set of DXF commands (e.g. 2D polyline)
    - No support is given (only resources are BiscoDxf manual and R14 DXF Reference)
