Unités physiques
R2026bSimscape™ contient une bibliothèque d’unités standard. Vous pouvez définir des unités supplémentaires si besoin. Vous spécifiez les unités ainsi que les valeurs des paramètres dans les boîtes de dialogue des blocs. Le gestionnaire d’unités de Simscape effectue les opérations de conversion d’unité nécessaires lors de la résolution d’un réseau physique. Les blocs Simscape supportent les systèmes de mesure standard. Les unités par défaut des blocs sont les mètres-kilogrammes-secondes ou MKS (SI).
