Why am I getting this error??? I want to observe conduction heat transfer on Stacked Cylindricall Cells. I keep getting the same error;
Check for missing argument or incorrect argument data type in call to function 'thermalProperties'.
Error in bugnshaf (line 26) ''thermalProperties(modelc,'ThermalConductivity',k,'SpecificHeat',Cp,'MassDensity',rho)''
My codes
modelc = createpde('thermal','transient');
modelc = createpde
gm = multicylinder(0.28,[0.724 0.802 0.702 3.353],'ZOffset',[0 0.724 1.526 2.228])
modelc.Geometry = gm
pdegplot(modelc,'CellLabels','on','FaceAlpha',0.99)
subplot(1,2,2)
pdegplot(model,'FaceAlpha',0.25,'FaceLabel','on')
figure
mesh_Hmax = generateMesh(modelc,'Hmax',0.056)
pdemesh(mesh_Hmax)
% thermal material properties.
k = 40.3; % Thermal conductivity, W/(m*C)
rho = 7715; % Density, kg/m^3
cp = 441; % Specific heat, W*s/(kg*C)
q = 0; % Heat source, W/m^3
thermalProperties(modelc,'ThermalConductivity',k,'SpecificHeat',cp,'MassDensity',rho)
thermalBC(modelc,'Face',1,'Temperature',185);
thermalBC(modelc,'Face',2,'Temperature',255)
thermalBC(modelc,'Face',3,'Temperature',295)
thermalBC(modelc,'Face',4,'Temperature',205)
thermalBC(modelc,'Face',5,'Temperature',255)
thermalBC(modelc,'Face',6,'Temperature',175)
thermalBC(modelc,'Face',7,'Temperature',200)
thermalBC(modelc,'Face',8,'Temperature',75)
thermalBC(modelc,'Face',9,'Temperature',175)
thermalIC(modelc,25)
tlist = 0:100:3000;
R = solve(modelc,tlist);
figure
pdeplot3D(modelc,'ColorMapData',R.Temperature(:,4))

You are overwriting modelc immediately after creating the thermal model. Remove the second line: modelc = createpde

I ran your code after removing the line I mentioned and got the following result. No error.
