آشنایی با مثال‌های Geant4

آشنایی با مثال‌های Geant4

در Geant4 سه مدل مثال تعریف شده است:

    v     Basice: مثال‌های بسیار ساده‌ای هستند که برای کاربران تازه کار بسیار مفید خواهند بود. با مطالعه این مثال‌ها کاربر آشنایی نسبتاً خوبی با اجزای مختلف Geant4 پیدا خواهد کرد.

     v     Extended: مجموعه‌ای از مثال‌هایی هستند که نیاز به کتابخانه‌های بیشتری دارند و موارد خاصی در آن جای گرفته است.

    v     Advanced: برنامه‌های کاربردی به صورت مثال‌های کاملی در آن قرار دارند. البته کاربران می‌توانند با توجه به نیاز خود آنها را اصلاح نماید.
