CFX! Rules for Expressions Rules for expressions Variables and expressions are case sensitive Always use brackets to specify the order of operations For multiple line expression, use operators to separate each line e. g, A+ B/C A+ B /C Expressions must be dimensionally consistent for addition and subtraction operations 1.0/mm7+0.45/yvds7 (valid) >2,5/3m~-1-(3.0ms^-1^~1 (valid) 0/mm7+0.3/kg invalid) 5.5 2001AEA TechnologyCFX 5.5 © 2001AEA Technology 4-4 Rules for Expressions Rules for Expressions - Variables and expressions are case sensitive - Always use brackets to specify the order of operations - For multiple line expression, use operators to separate each line > e.g., A+ B/C A+ B /C - Expressions must be dimensionally consistent for addition and subtraction operations > 1.0[mm] + 0.45[yds] (valid) > 2.5[s m^-1] - (3.0[m s^-1])^-1 (valid) > 1.0[mm] + 0.3[kg] (invalid)
