توضیحاتی در مورد کتاب برنامه نویسی عناصر مرزی 2 بعدی/3 بعدی در مهندسی نفت و ژئومکانیک

برنامه نویسی عناصر مرزی 2D/3D در مهندسی نفت و ژئومکانیک، جلد 72، به گونه ای طراحی شده است که شروع نوشتن برنامه های عناصر مرزی را برای محققان، مهندسان و دانشجویان آسان کند. این مرجع مبانی، تحولات نظری، برنامه نویسی و کاربردها را پوشش می دهد. هم جریان سیال از طریق محیط متخلخل و هم مشکلات ساختاری برای تمرین های کدگذاری استفاده می شود. برنامه های کامپیوتری شامل ممکن است به عنوان کدهای شروع استفاده شود. پس از اصلاحات، می توان آنها را برای مشکلات دنیای واقعی اعمال کرد. این کتاب موضوعاتی پیرامون تولید مش، کدگذاری عناصر مرزی سه بعدی، و کدگذاری رابط برای کنترل تولید مش و رسم نتایج را پوشش می‌دهد. شامل تمرین‌های کدگذاری تعاملی دو بعدی و سه بعدی است که خوانندگان می‌توانند بر اساس نیاز آن‌ها را اصلاح کنند.


توضیحاتی درمورد کتاب به خارجی

2D/3D Boundary Element Programming in Petroleum Engineering and Geomechanics, Volume 72, is designed to make it easy for researchers, engineers and students to begin writing boundary element programs. This reference covers the fundamentals, theoretical developments, programming and applications. Both fluid flow through porous media and structural problems are used for coding exercises.
