Hi,

How does STEP function work in CEL setup in CFX5.5?

Can some one who has used this function briefly explain.

thanks joseph

Hi Joseph,

the step function returns a value of 0 if the expression it evaluates is negative. It returns a value of 1 if the expression it evaluates is positive. A value of 0.5 is returned if the expression is 0. Note that the expression should be dimensionless, for example, step(x/1[m]) returns 0 for x<0 0.5 for x=0 1 for x>0 assuming the dimensions of x are [m].
