Fire Dynamics Simulator and Smokeview Fire Dynamics Simulator (FDS) is a computational fluid dynamics (CFD) model of fire-driven fluid flow. The software solves numerically a form of the Navier-Stokes equations appropriate for low-speed, thermally-driven flow, with an emphasis on smoke and heat transport from fires.Smokeview (SMV) is a free and open source visualization program that will help you display the output of FDS and CFAST simulations. What's New in This Release: · New output quantity: Fractional Effective Dose (FED) by Purser. · TIME INTEGRAL statistics is availale for device outputs. · Yields of any explicitly-defined (via the SPEC line) gas species can be specified on the MATL lines using the new parameter NU_GAS. · The user can specify how the sprinkler pipe pressure depends on the number of open nozzles. The flow rate, droplet speed and median diameter are updated correspondingly. · The logical keyword DRY has been added to DEVC. When using the mixture fraction and specifying either MASS FRACTION or VOLUME FRACTION, use of DRY will give that fraction minus water vapor (i.e. give an output like a typical gas analyzer). · A Phase Doppler Particle Analysis (PDPA) device has been defined for detailed measurements of droplet sprays. · A new namelist group called MULT (short for multiplier) allows you to multiply OBSTructions and MESHes easily without having to retype the input lines over and over. · A new parameter called BULK_DENSITY has been added to the OBST namelist group to indicate more easily the total combustible mass within an OBSTruction that can BURN_AWAY. · Pressure ZONEs can now be opened, and sealed compartments can become unsealed via an OPEN boundary. · The output quantity that was once called 'soot density' and the newer version, QUANTITY='DENSITY', SPEC_ID='soot', is now in units of kg/m^3. · Device (DEVC) output units can be changed via a CONVERSION_FACTOR.
