Hi -

   Did you try the expression without min(.) to verify that min is the problem?   Min may not exist in the set of functions implemented (currently), but could be added.

Cheers
Mike

Hi everyone,

I am looking for a way to define initial conditions which contain min() function. Can someone point to an example/syntax for the same? I am currently getting an error saying 

Message : Equation::Equation() fails on expression
 [(0.25*(1+cos(PI*min(sqrt(pow(x-bell_x0,2) + pow(y-bell_y0,2))/bell_r0, 1.0))))]

Thanks
V
