Re: How to define the hydrogen liquid?

Dear Mr. Fasso',
     In fact, before I define the HLIQUID, I have defined water and air
material(this input file for fluka courses is obtained from the fluka
site,the water and air material has been defined before), namely, they
will be assigned the material number 26 and 27. So the material HLIQUID
will assigned the number 28. On the other hand, I also leave the
material number blank and run this input file, I got the same error. So
I believe that it is not wrong with material number. Can you to check it
again?
Thank you very much!

                        Best regards,
