Simplify the problem - Simplify geometry > Ignore features that do not affect the flow > Use as many blocks as possible to set the geometry > Make blocks meet at complete faces

The initial tolerance is important for geometry construction and grid construction. The preferred method to set the tolerance is to work from the Preferences pull down menu and select Global

Ⅰ. Background Information 1. Richard Wagner (1813-1883), the greatest composer of German opera, made a major addition to the nature of opera through his writings about and the creation of music drama.

一、集合 (Set) 1.集合概念 2. 集合的运算

Computational geometry Algorithms for solving “geometric problems” in 2D and higher. Fundamental objects: point line segment line Basic structures: point set polygon

Definition: Group A set G of elements and operator @ form a group if: for all x,y in G, x @ y is also in G (inclusion) there is an identity element e such that for all x in G, e@x = x for all x in G, there is an inverse element x

Goal Concept: A concept definition describing the concept to be learned. (It is assumed that this concept definition fails to satisfy the Operationality Criterion.) Training Example: An example of the goal concept. Domain Theory: A set of rules and facts to be used in explaining how the training example is an example of the goal concept
