automesh子面板详细解释

?Quadsonly uses a subdividing routine that tends to generate more orthogonal quad elements. Tria elements may still be introduced depending on the density settings as with the quads type. ?Tria elements uses all-trias to mesh. ?R-trias are right-angle triangular elements. If you select Advanced, choose any of the other types individually for mapped elements (elements on surfaces that can be mapped to simple geometric shapes) and free elements (those that cannot easily map to simple shapes). mapped type Choose the type of elements (as for Mesh type above) to use for surfaces that can be mapped to simple geometric shapes. map as circle - free map as circle - mapped map as rectangle - free map as rectangle - mapped map as pentagon - free map as pentagon - mapped free type Choose the type of elements (as for Mesh type above) to use for surfaces that cannot be mapped to simple geometric shapes. feature angle Specify a maximum angle across which elements can be maintained. Any time two adjacent elements’ normals would exceed this angle HyperMesh creates a new set of nodes between them to maintain clean feature lines. Using a higher value results in elements spanning the feature line: With an appropriate value, the features lines are preserved. If feature angle = is too high, the feature lines are blurred. vertex angle When using connected features or auto detect features, this setting is a maximum element vertex angle. Whenever an element vertex exceeds this angle while adhering to features, the element will be split into two elements with correspondingly smaller vertices. elems to surf comp / elems to current comp Select the destination component for the newly created elements as the “current” active component or the component to which the surface belongs. The current component is indicated in the component list of the Model browser, or the component status display of the status bar. first order /second order Set to create first order (linear shape function) or second order (polynomial shape function) elements. connectivity Select how the connectivity between the newly created elements and any adjacent existing elements will be handled. Choices include: ?keep connectivity: use the existing nodes on any shared boundary edges. ?redo connectivity: re-seeds any existing nodes along the boundary of the newly created mesh to optimize mesh quality. ?break connectivity: ignore any existing adjacent elements
