20080246766 | NUMERICAL ANALYSIS MESH GENERATING METHOD AND APPARATUS - The triangular mesh generating portion divides the surface of geometry model to be meshed in a meshed manner according to a target element dimension and generates a triangular mesh on the surface of geometry model. The regular mesh generating portion assumes a shaped parallelpiped enclosing the shape to be meshed. The parallelpiped is divided in a meshed manner by the hexahedral element whose distance between the nodes has the substantially same density as the triangular mesh on the surface. The resulting regular mesh located inside the triangular mesh on the surface of geometry model is divided into a tetrahedral meshed manner. The shell meshing area extracting portion extracts a shell-like space between the inner tetrahedral mesh and the triangular mesh on the surface of geometry model. The shell mesh generating portion generates the tetrahedral mesh in the overall shape to be meshed. | 10-09-2008 |

20090262110 | GEOMETRIC MODELING SYSTEM AND OPTIMIZATION METHOD FOR GEOMETRIC FITTING - A system is provided for creating a modified analytical model from an existing analytical model and CAD data (geometric model data) of the modified model to reduce the workload in creating geometric and analytical models. The system includes means for reading a geometric model and an analytical model which are to be modified; means for storing correlation data showing relations between geometric elements of the object geometric model and nodes of the object analytical model; means for modifying the object analytical model to create a modified analytical model; and means for extracting geometric elements of the object geometric model which do not include the nodes in the modified object analytical model related to the object geometric model's geometric elements extracted from the correlation data and performing geometric fitting so as to fit the extracted geometric elements to the nodes to create a modified object geometric model from the modified analytical model. | 10-22-2009 |
20100138195 | ANALYSIS MESH GENERATION APPARATUS - The conventional technologies are impractical for the following reason. CAD has been the only solution for changing an analysis model with adding or deleting a fillet. In this case, it is necessary to repeat the mesh generation and condition configuration, which makes the work time longer especially for large-scale or complicated shape data. The present invention, accomplished to solve the above-mentioned problem, provides an analysis mesh generation apparatus including a computer for generating a mesh model. The apparatus is configured to create a screen for selecting an edge of a mesh model and entering a radius of a fillet to be applied to the selected edge; and to create a screen for generating a mesh for the applied fillet, generating a new mesh model by deleting or adding an area enclosed by a contour of the mesh model and the fillet, and displaying the new mesh model. | 06-03-2010 |

A mesh generation system designates an evaluation point (site) on an analysis target shape, analyzes plural analysis model data created with plural types of mesh size, stores a relation among mesh size, analysis result and calculation time in a mesh know-how DB, search for a mesh size which meets a required accuracy and calculation time limit, sets the mesh size that is found by the search to an analysis model. And displays the relation among mesh size, analysis result and calculation time. | 08-29-2013 |
20130321415 | Analytical Model Information Delivery Device and Analytical Model Information Delivery Program - Using this analytical model information delivery device, it is possible to quickly create analytical models even when the designer and the analyst are different people. This analytical model information delivery device is provided in a device for creating numerical models from CAD data. A shape search unit searches the components making up the CAD data and extracts features, and matches the extracted features with shape creation rules pre-registered in an analytical modeling means database. Further, when modifying a three-dimensional CAD model using the shape creation rules, an input result display unit highlights the modification area of the three-dimensional CAD model modified in accordance with the shape creation rules. A model conversion unit creates a numerical model from the modified three-dimensional CAD model. A shape processing unit further interactively modifies the modified area of the numerical model displayed by a modeling area display unit. | 12-05-2013 |
