Mechanical stress in a structure due to its own gravitational load

Hi all,

I want to calculate the mechanical stress distribution in a structure that is due to its own load under gravity. In the pdetool in Matlab, it is not possible to enter density-dependent forces. How can I implement this problem?

Thanks!

E = 227E9; % in Pa

nu = 0.27; % Dimentionless

structuralProperties(wStructure,"YoungsModulus",E,'PoissonsRatio',nu,'MassDensity',7800);

structuralBodyLoad(wStructure,"GravitationalAcceleration",[0;0;-9.8]);

% try doing this
