Incorrect effective wind speed reported for two-fuel model options and specified direction of spread

Two-fuel spread direction bug
Description Version 5.0 Beta1 (Build 289) produces wrong flame lengths for SURFACE with two-fuel model and input spread direction options. Beta2 (Build 290) is a partial fix. Correct flame length values are calculated for the two-fuel model option when a single value of spread direction is input. Multiple spread direction values are still a problem for the two-fuel model option. The bug does not occur when using a single fuel model.
Reported Version 5.0 Beta1 Build 289 and Beta2 Build 290, December 2009
Status Fixed in Version 5.0.0 Build 295 on April 9, 2010
