Re: How to define the hydrogen liquid?

I am sorry, I had not noticed that the input was in attachment.
The error is due to the fact that you have assigned an index 28
to material HLIQUID. The sequence of material numbers must not be
interrupted: but besides the predefined materials (numbers 1 to 25)
no material 26 and 27 are present.
You may modify the number to 26, or even better leave it blank (the program
will assign a number automatically, since your input is name-based).
Please read the Notes to command MATERIAL in the manual for a detailed
explanation.
