A board design aid device includes a calculating and correcting units. The calculating unit groups a plurality of layers in a multi-layer board into a plurality of pairs of layers based on design information of the multi-layer board, the plurality of layers being stacked and derives a difference of total amounts in respect to a board design element, each of the total amounts being related to each layer of a pair of layers of the plurality of pairs of layers, the board design element being related to a warp of the multi-layer board. The correcting units, based on the difference of the total amounts, corrects an amount of the board design element for at least one of layers among at least one of the plurality of the pairs of layers so that the difference of the total amounts of the board design element is maintained within a certain range.

An analysis model control unit disposes at least two component models, which are to be used in assembly of a product to be evaluated, in virtual space displayed on a screen. A virtual glove controller moves and operates component models, which are disposed in virtual space, in accordance with an input operation signal of a user by a virtual glove. When the two component models are brought into contact with each other, a model conversion unit converts them into component analysis models. A deformed structure analysis unit executes structure analysis calculations with respect to the relative movement caused along with assembly of the two component analysis models after contact so as to calculate deformation and deformation stresses. An evaluation processing unit compares the deformation stress with a threshold stress of the material so as to evaluate whether assembly can be performed without breaking the components.

A structural analysis apparatus automatically sets a boundary between an entire model and a detailed model to thereby obtain a highly accurate solution without intervention by an operator and with fewer man-hours and shorter calculation time. An iso-surface creation step creates a field iso-surface from an analysis result of a mesh model. A detailed mesh model creation step uses the field iso-surface created by the iso-surface creation step to create a detailed mesh model of a part of the mesh model. An analysis step uses the analysis result of the mesh model to perform analysis of the detailed mesh model created by the detailed mesh model creation step. An analysis evaluation step evaluates the analysis result of the detailed mesh model based on the analysis result obtained by the analysis step and analysis result of the mesh model.
