Hi all,
I was trying to plot heat flux lines for a heat transfer problem. The problem specifies a 0.3m by 0.1m rectangular plate. Its right, left and bottom edges are kept at 273.15K and the top edge has a temperature distribution:
with thermal conductivity, k=2.5 W/mK. I've tried the following to solve this problem:
load('gd');load('ns');load('sf');g=decsg(gd,sf,ns);thermalmodel = createpde('thermal');geometryFromEdges(thermalmodel,g);pdegplot(thermalmodel,'EdgeLabels','on')xlim([0 .3])ylim([0 .15])axis equaldx=.0001;x=0:dx:.3;thermalProperties(thermalmodel,'ThermalConductivity',2.5,'Face',1);thermalBC(thermalmodel,'Edge',1,'Temperature',273.15);thermalBC(thermalmodel,'Edge',2,'Temperature',273.15);thermalBC(thermalmodel,'Edge',4,'Temperature',273.15);thermalBC(thermalmodel,'Edge',3,'Temperature',30.*sin(pi.*x/.3));generateMesh(thermalmodel);results = solve(thermalmodel)
I'm getting the following error: Error using pde.ThermalBC/set.Temperature (line 136)
Temperature for all specified edges or faces must be a scalar value or a single function handle. Could someone suggest how I can impose the variable temperature distribution?
