In a biological simulation apparatus, an operation unit represents a structure domain where tissues of a biological organ exist by a structure mesh model based on a Lagrange description and a fluid domain where fluid inside the biological organ exists by an ALE fluid mesh model based on an ALE description method. In a fluid-structure interaction simulation, the operation unit deforms the structure mesh model, and then deforms the ALE fluid mesh model so as to form no gap on a first interface between a domain where a site other than a certain site of the biological organ in the structure domain exists and the fluid domain or no overlap with the structure domain. The operation unit captures a position of a second interface between a domain where the certain site exists and the fluid domain by using the ALE fluid mesh model as a reference.

A visualization apparatus detects a change in the shape of a solid model of a human body part based on images obtained by capturing the solid model. Next, the visualization apparatus generates a three-dimensional model reproducing the shape of the human body part in virtual space based on three-dimensional model data representing the shape of the human body part in three dimensions. The visualization apparatus further transforms the shape of the three-dimensional model into a transformed three-dimensional model in accordance with the change in the shape of the solid model. Then, the visualization apparatus outputs images of the transformed three-dimensional model.

Next, the excitement propagation visualization apparatus detects for each analysis time an intersection of a straight line passing through a first point inside a heart and a second point outside the heart and the excitement propagation wave front. Furthermore, the excitement propagation visualization apparatus generates for each analysis time a display object associated with the intersection of the straight line and the excitement propagation wave front.

A streakline visualization apparatus sets a partial region including a discrete point at a first position on a first streakline in an analysis space as an analysis target region of the discrete point. Based on a velocity of fluid in the analysis target region indicated by fluid information, the apparatus calculates a second position indicating a destination of a particle on the discrete point at a second analysis time point. Next, based on information about a structure in the analysis target region indicated by structure information, the apparatus determines a region occupied by the structure in the analysis target region at the second analysis time point. Next, based on the first and second positions, the apparatus determines whether a second streakline has entered the occupied region. If the second streakline has not entered the occupied region, the apparatus displays the second streakline passing through the second position.
