I intend to ask the following question:

Can I install Geant4 (wiki) alongside GEANT-3 (wiki) on my Ubuntu 15.04? I have already installed GEANT3. How can I install Geant4 without making any problems?

Can I ask the question on Physics StackExchange? May be we should introduce a tag or site for computing packages and resources for physics.

I have already asked similar question on StackOverflow Meta here.

  • $\begingroup$ It's probably more appropriate for the Computational Science Stack Exchange. We generally discourage questions about software on the grounds they're not directly about physics. You could try asking in the Physics chat. Is there no support community for the software? $\endgroup$ – John Rennie Jul 6 '15 at 7:29
  • $\begingroup$ I would agree with the Meta SO answer that SU/AU/UL are probably better options (since it is about installing the software and not using it) $\endgroup$ – Kyle Kanos Jul 6 '15 at 12:07

    $\begingroup$ On the other hand, Physics is more likely than Comp Sci to contain somebody who has actually installed and used Geant - it isn't exactly common software that everyone uses (unless you are interested in rad transport). $\endgroup$ – Jon Custer Jul 6 '15 at 13:32
  • $\begingroup$ The answer to your question is that they share almost nothing and you can probably just go ahead. $\endgroup$ – dmckee --- ex-moderator kitten Jul 6 '15 at 15:07
  • $\begingroup$ How do you know that they share nothing? I mean I do not question your knowledge but I also want to understand how you really know this. $\endgroup$ – MycrofD Jul 7 '15 at 9:39

    $\begingroup$ Because Geant4 is a major re-write in a new language. Geant3 was a fortran 77 framework (which paired well with CERNLIB) and Geant4 is c++ framework (and pairs reasonably well with ROOT and with a few other modern analysis frameworks). There may still be a small about of fortran code still hanging around in odd corners of Geant4, but there isn't much. $\endgroup$ – dmckee --- ex-moderator kitten Jul 7 '15 at 21:40
