Yes the documentation explainning the meaning of this constructor’s parameters
does not exist. I think @agheata can point you to the right place. Then we might improve the documentation of this constructor.

Thank you i will wait.

Hi, these are the atomic mass, atomic number and the material density in g/cm3. We’ll need to review the documentation for the material classes
