1、单选题:
Steps at the math modeling are( )。
选项:
A:Developing finite-difference schemes (finite-elements scheme) for numerical solution of the problem under consideration.
B:Quality’s analysis of uniqueness solution or multiplicity of the problem solution. For this aim, as a rule, the pointwise model is derived from PDEs.
C:Analysis of physical units of each terms involving in the equations.
D:Introducing dimensionless variables and writing similarity parameters (π - parameters).
E:Analysis of the physical and chemical processes occurring in process under consideration.
F:Derivation of the conservation laws (integrals of motions) for the problem under consideration.
G:Writing of the differential (and other) equations describing the process under consideration.
