The Cell Method (CM) is a computational tool that maintains criticalmultidimensional attributes of physical phenomena in analysis. Thisinformation is neglected in the differential formulations of the classicalapproaches of finite element, boundary element, finite volume, and finite difference analysis, often leading to numerical instabilitiesand spurious results. This book highlights the central theoretical concepts of the CM thatpreserve a more accurate and precise representation of the geometricand topological features of variables for practical problem solving. Important applications occur in
