Function Documentation

int Roth1972FireSpreadGetAtAzimuth ( RothFuelModel * rfm, double az )

Step 4 of FireSpread Pipeline. Calculates the rate of spread through the fuel bed in the direction specified as an argument. RothFuelModel units must be ENGLISH. Steps 1, 2, and 3 in FireSpread Pipeline must have been completed without error prior to calling this function. See also: RothFuelModel Parameters: rfm   RothFuelModel structure containing fuel particle attributes az   azimuth in the direction which rate-of-spread is calculated Return values: ERR_SUCCESS   (0) if operation successful, an error code otherwise Note: Best use of this facility is as follows: int error_status = SomeFunctionXXX(); if ( error_status ) // something bad happened Definition at line 520 of file Roth1972.c.

int Roth1972FireSpreadNoWindNoSlope ( RothFuelModel * rfm, double d1hfm, double d10hfm, double d100hfm, double lhfm, double lwfm )

Step 2 of FireSpread Pipeline. Calculates the NoWind-NoSlope rate of spread through the fuel bed represented by RothFuelModel. RothFuelModel units must be ENGLISH. Step 1 in FireSpread Pipeline(SetFuelBed) must have been completed prior to calling this function, however calling SetFuelBed prior to every call to NoWindNoSlope is unnecessary. Instead, SetFuelBed need only be called when any of the fuel particle attributes (load,sav,dens,hc,stot,seff) have changed. See also: RothFuelModel Parameters: rfm   RothFuelModel structure containing fuel particle attributes d1hfm   dead 1 hour fuel moisture d10hfm   dead 10 hour fuel moisture d100hfm   dead 100 hour fuel moisture lhfm   live herb fuel moisture lwfm   live woody fuel moisture Return values: ERR_SUCCESS   (0) if operation successful, an error code otherwise Note: Best use of this facility is as follows: int error_status = SomeFunctionXXX(); if ( error_status ) // something bad happened Definition at line 163 of file Roth1972.c.

int Roth1972FireSpreadSetFuelBed ( RothFuelModel * rfm )

Step 1 of FireSpread Pipeline. Converts RothFuelModel structure containing individual fuel particles comprising fuel bed into a single representative fuel bed. If RothFuelModel units are METRIC, then converts values to ENGLISH. See also: RothFuelModel Parameters: rfm   RothFuelModel structure containing fuel particle attributes Return values: ERR_SUCCESS   (0) if operation successful, an error code otherwise Note: Best use of this facility is as follows: int error_status = SomeFunctionXXX(); if ( error_status ) // something bad happened Definition at line 32 of file Roth1972.c. Referenced by InitRothFuelModelListFromProps().

int Roth1972FireSpreadWindSlopeMax ( RothFuelModel * rfm, double wnd_fpm, double wnd_az, double slp_pcnt, double asp )

Step 3 of FireSpread Pipeline. Calculates the maximum rate of spread through the fuel bed given the supplied wind and slope related arguments. RothFuelModel units must be ENGLISH. Steps 1 and 2 in FireSpread Pipeline must have been completed without error prior to calling this function. See also: RothFuelModel Parameters: rfm   RothFuelModel structure containing fuel particle attributes wnd_fpm   midflame windspeed in ft/min wnd_az   azimuth from which wind is coming (same as measured by RAWS) slp_pcnt   slope percent (as whole number eg 100 corresponds to 100% slope or [1 unit rise]/[1 unit run] ) asp   aspect (eg direction of maximum rate of change of slope aka downslope) Return values: ERR_SUCCESS   (0) if operation successful, an error code otherwise Note: Best use of this facility is as follows: int error_status = SomeFunctionXXX(); if ( error_status ) // something bad happened Definition at line 331 of file Roth1972.c.
