Variableninitialisierung
Der Simscape™-Solver berechnet die Anfangsbedingungen für die Modellsimulation, indem er Anfangswerte für alle Systemvariablen findet, die alle Modellgleichungen erfüllen. Sie können die Berechnung der Anfangsbedingungen beeinflussen, indem Sie die Priorität und die Zielanfangswerte für Blockvariablen festlegen. Sie können auch von einem gespeicherten Arbeitspunkt aus Variablen für ein ganzes Modell initialisieren. Nach dem Initialisieren der Blockvariablen und vor der Simulation des Modells können Sie im Variablen-Viewer prüfen, welche der Variablenziele erfüllt wurden.
