However, I am not quite sure what the properties of a newly created material should be in order its particles to be massless. I mean, it is not possible to put a zero value in density. Should I put an extremely small value for the density instead? Or is there another trick? I have read the documentation (nothing is mentioned) and similar posts, but all discussions end without giving an explicit practical answer/suggestion on this issue. Thank you in advance
