Input of solid angle in flair

Dear Fluka Expert,

When the solid angle is Π, my input in flair is wrong, as shown in the figure below. What should be the correct input?


Dear Li,

you have to options:

  1. you can input the numerical value of pi (3.1415…), or
  2. you can add the Flair expression: =1.0*pi


I missed an equal sign. Thank you
