<strong>SIMEA</strong> Stato dell’arte energetica <strong>degli</strong> e<strong>di</strong>fici<br />
1.3.12. Therm<br />
Analysis of two-<strong>di</strong>mensional heat transfer through buil<strong>di</strong>ng<br />
products. Includes a graphical user interface that allows users to<br />
draw cross sections of fenestration and other buil<strong>di</strong>ng products,<br />
which can then be analyzed by an automatic mesh generator and<br />
finite-element heat transfer algorithms. Results are <strong>di</strong>splayed<br />
graphically.<br />
1.3.12.1. Expertise Required<br />
Understan<strong>di</strong>ng of heat flows through buil<strong>di</strong>ng products;<br />
knowledge of properties of materials useful.<br />
1.3.12.2. Users<br />
Version 5.2 in use by over 1000 users internationally.<br />
1.3.12.3. Au<strong>di</strong>ence<br />
102<br />
Doc.No 20100610.<strong>SIMEA</strong>.MR.03<br />
Versione 1<br />
Buil<strong>di</strong>ng product developers, designers, analysts determining window ratings (NFRC).<br />
1.3.12.4. Input<br />
Graphic user interface; user enters cross sections of the buil<strong>di</strong>ng products, can read .DXF files and<br />
bitmaps.<br />
1.3.12.5. Output<br />
U-factors, isotherms, colour-flooded isotherms, heat-flux vector plot, and colour-flooded lines of<br />
constant flux.<br />
1.3.12.6. Computer Platform<br />
Requires Windows 98, Windows NT, Windows 2000, or Windows XP. Pentium or better. At least<br />
64MB of random access memory (RAM), 128 MB of RAM is preferred for optimum operation. Hard <strong>di</strong>sk<br />
drive with at least 15 megabytes of available <strong>di</strong>sk space.<br />
1.3.12.7. Programming Language<br />
C, FORTRAN<br />
1.3.12.8. Strengths<br />
State-of-the-art user interface; automatic meshing/re-meshing completely user transparent; advanced<br />
ra<strong>di</strong>ation and convection models can be incorporated into the finite element analysis algorithms used. The<br />
current version is 32-bit, which is faster than previous versions.
