创建一个热模型，包括一个正方形的几何形状。

thermalmodel = createpde (“热”）;geometryFromEdges (thermalmodel @squareg);pdegplot (thermalmodel“EdgeLabels”，“上”) ylim([-1.1 1.1])轴平等的

图中包含一个坐标轴。轴包含5个对象的类型行，文本。

在正方形的边1和边3上应用温度边界条件。

thermalBC (thermalmodel“边缘”3 [1],“温度”, 100);

在正方形的边缘4上应用热流边界条件。

thermalBC (thermalmodel“边缘”，4，“HeatFlux”, 20);

检查边1的边界条件说明。

tbcaEdge1 = findThermalBC (thermalmodel。BoundaryConditions,“边缘”, 1)

tbcaEdge1 = ThermalBC with properties: RegionType: 'Edge' RegionID: [1 3] Temperature: 100 HeatFlux: [] ConvectionCoefficient: [] Emissivity: [] AmbientTemperature: [] Vectorized: 'off'

检查边3和边4的边界条件说明。

tbca = findThermalBC (thermalmodel。BoundaryConditions,“边缘”[3:4]);tbcaEdge3 = tbca (1)

tbcaEdge3 = ThermalBC with properties: RegionType: 'Edge' RegionID: [1 3] Temperature: 100 HeatFlux: [] ConvectionCoefficient: [] Emissivity: [] AmbientTemperature: [] Vectorized: 'off'

tbcaEdge4 = tbca (2)

tbcaEdge4 = ThermalBC with properties: RegionType: 'Edge' RegionID: 4 Temperature: [] HeatFlux: 20 ConvectionCoefficient: [] Emissivity: [] AmbientTemperature: [] Vectorized: 'off'
