Найти граничные условия и краевые нагрузки, присвоенные геометрической области
sbca = findStructuralBC(structuralmodel.BoundaryConditions,RegionType,RegionID)RegionType и RegionID. Функция возвращает структурные граничные условия, назначенные structuralBC и краевые нагрузки, присвоенные structuralBoundaryLoad.
Найдите граничные условия несущих конструкций для граней 3-D геометрии.
Создайте несущую модель и включите блок геометрию.
structuralmodel = createpde('structural','static-solid');
Включите в модель блока геометрию и постройте график геометрии.
importGeometry(structuralmodel,'Block.stl'); pdegplot(structuralmodel,'FaceLabels','on','FaceAlpha',0.5)
Задайте поверхностную тягу на грани 1 блока.
structuralBoundaryLoad(structuralmodel,'Face',1,'SurfaceTraction',[100;10;300]);
Задайте давление на грани 3 блока.
structuralBoundaryLoad(structuralmodel,'Face',3,'Pressure',300);
Применить свободное ограничение к граням 5 и 6 блока.
structuralBC(structuralmodel,'Face',[5,6],'Constraint','free');
Проверьте спецификацию граничных условий для граней 1 и 3.
