How to define variable parameters in Flair

[mbathamlp35 (Mbatha Molapo)]

Hi. I’m new to FLUKA and i’m trying to define an input file to calculate linear attenuation coefficient of lead over a range of thicknesses (1 cm up to 10 cm with a step of 1 cm) for a 1 MeV photon beam. However, I have noticed that in Flair the thickness is defined by min and max values (ymin and ymax in my case). How can I modify this to run simulations over the specified thickness range?

Dear Mbatha,

please have a look at

Fluka can implement a 'for loop' ? like C++

Dear Tian, You can define variables with the #define card and then use the Loop feature on Flair’s Run/Runs tab to set up separate simulations for the different values. Cheers, David
