    Abstract: A vehicle steering control apparatus includes an actuator to vary a steering gear ratio of a vehicle wheel steer angle of a steerable wheel to a steering wheel angle. A controller controls the actuator to produce an actuator torque in a steering direction at a start of a driver's steering operation.

    Abstract: Before the execution of simulation, variation rates at the grid points of functions for the calculation of intersections between grid points and the surface of the shape to be analyzed of a simulation model are calculated; new grid spacings are calculated by performing calculation so that the greater the variation rate the narrower the grid spacing; and where, with respect to these grid spacings, aspect ratios far deviate from 1, finite difference grids are automatically optimized by adjusting the grid spacings so that the aspect ratios approach 1. Furthermore, during the execution of simulation, the variation rates of functions, whose values are physical quantities at different grid points, are calculated, and finite difference grids are automatically optimized by performing calculation so that the greater the the variation rate the narrower the grid spacing.
