The unit of the signal variables is always null.?This dimensionless unit has the main advantage to be compatible will all other units.?It is then possible to connect a null signal to a submodel requiring a variable having a physical unit, like bar or m/s.?Note that is such case, the signal is directly transferred without any unit conversion.信号变量的单位总是“空”。这个无因次单位的主要优势都将其他单位兼容。然后可以将一个空的信号连接到子模型需要一个变量物理单位,比如bar或者m / s。注意,这种情况下,没有任何单位转换信号直接传输Even on blocks sending variables corresponding to time, like CLOC0, the output variable has a null unit.即使在块发送变量对应于时间,像CLOC0,输出变量有一个空单元。Figure 1: CLOC0 submodel output variable3. Sources, Sinks This sub category contains the signal sources and signal sinks. The source components do not depend on any other input than time, and produce simple or complex signals. Most source icons consist of a circle containing the type of signal to be delivered.3。源、汇这个子目录包含信号和信号接收来源。源组件不依赖于任何其他比时间输入,并产生简单的或复杂的信号。大多数源图标由一圈包含信号传递的类型。Signals can be either continuous (sine wave...) or discrete (square wave...). Note that some sources like the sine wave SIN0 use to reduce automatically the maximum time step of the solver. For instance, SIN0 reduces it to T/4 with T the period of the sine wave. Using such a source in a model may then have an influence on the behaviour of the simulation. Most submodels altering the maximum time step indicate the change by a warning message. Some source components contain some input ports. These allow some variable characteristics of the signal generated by the source. For instance, a sine wave with variable frequency.信号可以是连续的(正弦波…)或离散(方波……)。注意,一些来源如正弦波SIN0使用减少自动解算器的最大时间步。例如,SIN0减少它4 T / T的正弦波。在模型中使用这样的来源可能会有影响的行为模拟。大多数子改变的最大时间步表明变化的警告消息。一些源组件包含一些输入端口。这些允许一些变量的特点生成的信号来源。例如,一个正弦波变频。Figure 3: source component having an input portThe sinks are used to terminate signal lines. Some sinks can play an important role like STOP0 which terminates the simulation under certain conditions or SIGWRITE0 and SIGWRITE1 that write the value of
