  The outflow destination deriving unit 140 selects a small unit from which the wind flows out from one small unit as a base point based on the one small unit wind information from among small units (groups) in the vicinity of the one small unit. To derive (select). One small unit may be set in advance, may be determined based on data regarding the small unit that is the first base point input from the input unit 10, or may be determined by the user via the input / output device 103. It may be set interactively. The neighborhood is, for example, a small unit in contact with one small unit (a vertex, a side, or a surface). FIG. 5 is a diagram showing a small unit in the vicinity of a target small unit. In FIG. 5, among the 27 small units in total of 3 in the width direction, 3 in the depth direction, and 3 in the height direction, one small unit based on the small unit at the center (colored) I assume. In this case, the small units in the vicinity of one small unit are the remaining 26 small units in which one small unit is in contact with a vertex, a side, or a surface. In addition, the definition of the small unit in the vicinity is not limited to the above-described ones. For example, a small unit that is in contact with only one side or a surface (18 small units), or a small unit that is in contact with only one small unit and a surface. (6 small units), a small unit within a predetermined distance from one small unit, or the like may be used.

  The outflow destination deriving unit 140 derives a small unit in the vicinity where it is determined that the air flow is continuous based on one small unit of wind information as the small unit of the wind outflow destination. That is, the outflow destination deriving unit 140 derives a small unit of the outflow destination of the wind based on the air flow. For example, the outflow destination deriving unit 140 converts one or more small units among the small units in the vicinity based on at least one of the wind direction, the wind speed, and the pressure difference based on the wind information of one small unit. It is determined that the flow of is continuous. For example, the outflow destination deriving unit 140 sets a nearby small unit existing in a direction indicated by the wind direction based on the wind information of the one small unit, as a small unit of the wind outflow destination, with the center of the one small unit as a base point. It may be derived. The outflow destination deriving unit 140 may derive one or more small units among the small units in the vicinity as a small unit of a wind outflow destination from one small unit.

  The outflow destination deriving unit 140 may derive the small unit of the outflow destination of the wind based on the wind information of the nearby small unit. For example, the outflow destination deriving unit 140 may determine at least one or more of a wind direction, a wind speed, and a pressure difference based on wind information of one small unit, and a wind direction, a wind speed, and a pressure difference based on wind information of each small unit nearby. According to at least one or more of the above, one or more small units out of the neighboring small units are derived as small units of the wind outflow destination. For example, the outflow destination deriving unit 140 calculates the angle between the wind direction based on the wind information of one small unit and the wind direction based on the wind information of each small unit in the vicinity, and makes the smallest angle or a predetermined angle. The following small units in the vicinity may be derived as small units to which the wind flows. Further, for example, the outflow destination deriving unit 140 calculates the outflow amount of the wind based on the wind information of one small unit, and the inflow amount of the wind based on the wind information of each small unit in the vicinity, Based on the outflow amount of the small unit wind and the inflow amount of the wind in each small unit nearby, the small unit with the largest amount of wind inflow among the small units in the vicinity, or the inflow amount of the wind is greater than or equal to a predetermined threshold One or more small units that are may be derived as small units of the wind outflow destination.

  The continuous derivation unit 14 repeatedly executes the outflow destination derivation unit 140 using the small unit derived by the outflow destination derivation unit 140 as a base point. For example, when the outflow destination deriving unit 140 derives the small unit B of the wind outflow destination from the small unit A as the base point, the continuous deriving unit 14 subsequently changes the outflow destination deriving unit 140 from the small unit B as the base point. Run. Thus, when the outflow destination deriving unit 140 derives the small unit C of the wind outflow destination from the small unit B as the base point, the continuous deriving unit 14 subsequently continues to the outflow destination deriving unit 140 from the small unit C as the base point. Run. The continuous derivation unit 14 repeatedly executes the outflow destination derivation unit 140 as described above. In addition, for example, when the small unit B and the small unit C of the wind outflow destination are derived from the small unit A by the outflow destination deriving unit 140 (that is, when a plurality of small units are derived), for example Subsequently, the continuous deriving unit 14 executes the outflow destination deriving unit 140 using the small unit B as a base point, and executes the outflow destination deriving unit 140 using the small unit C as a base point. The continuous deriving unit 14 outputs the continuous small units obtained in the execution process by the outflow destination deriving unit 140 to the continuous small unit storage unit 15 and the airflow information display unit 16 described later.

  The continuous derivation unit 14 may repeatedly execute the outflow destination derivation unit 140, starting from a small unit in contact with the opening of the building, based on the data on the opening of the building input from the input unit 10. Moreover, the continuous derivation | leading-out part 14 may select the small unit used as the starting point based on the wind information of each small unit, when there exist multiple small units which contact | connected the opening part of the building. For example, the continuous deriving unit 14 may select a small unit having the maximum wind speed or a small unit equal to or higher than a predetermined wind speed as the small unit serving as a starting point.

  The continuous deriving unit 14 continues until the predetermined number of repetitions reaches the predetermined number of times, until the derived small unit becomes a small unit in contact with the opening of the building, or for each small unit derived, the wind information of the small unit It may be determined based on whether or not the air flow has diffused, and the outflow destination deriving unit 140 may be repeatedly executed until it is determined that the air flow has diffused. The continuous deriving unit 14 may acquire a predetermined number of repetitions based on data regarding the number of repetitions input by the input unit 10, or the continuous deriving unit 14 may interactively receive from the user via the input / output device 103. You may get it. Further, the continuous derivation unit 14 inputs data from the input unit 10 regarding the opening of the building (position information of the opening as to whether or not the derived small unit is a small unit in contact with the opening of the building. And the position of the derived small unit (for example, based on the “small unit position” shown in FIG. 4). Further, the continuous deriving unit 14 determines whether or not the airflow has diffused for each derived small unit based on one or more of the wind direction and the wind speed included in the wind information of the small unit. For example, the continuous deriving unit 14 determines that the airflow has diffused when the wind speed included in the wind information of the small unit is less than a predetermined wind speed for each small unit to be derived.

  The continuous small unit storage unit 15 stores information regarding continuous small units input from the continuous deriving unit 14. FIG. 6 is a view showing an example of a table stored by the continuous small unit storage unit 15. As shown in FIG. In the example of the table shown in FIG. 6, identification information (“airflow ID”) for identifying a continuous airflow, which is input from the continuous derivation unit 14, is a continuous airflow unit (based on one small unit) as one airflow. Allocated, one or more small unit small unit IDs included in the air flow are associated. For example, in the table example illustrated in FIG. 6, the airflow with the airflow ID “1” indicates that the small unit ID includes small units such as “1”, “3”, “7”, and “10”. ing.

  The airflow information display unit 16 is configured by a continuous small unit obtained in the process of execution by the continuous derivation unit 14, more specifically, a continuous small unit input from the continuous derivation unit 14 or a continuous small unit storage unit 15. The air flow information indicating the air flow based on the stored continuous small units is displayed. The airflow information display unit 16 may display the airflow information indicating the three-dimensional airflow in the building based on the continuous small units obtained in the execution process by the continuous deriving unit 14 in three dimensions.

Next, the outflow destination deriving unit 140 derives the small unit of the wind outflow destination from the one small unit, using the single small unit selected in S50 as a base point (step S51). Next, it is judged by the continuous derivation unit 14 whether or not the repetition condition of the execution process of the outflow destination derivation unit 140 is satisfied (step S52). If it is determined in S52 that the repetition condition is satisfied, the outflow destination deriving unit 140 executes the process of S51 again. The small unit serving as the base point at this time is the small unit of the flow-out destination of the wind derived in the previous processing in S51.
