Problem description

Model:

The models have dimensions 40.0 × 40 in the x–y plane, with an out-of-plane dimension of 5.0.

Material:

Modulus 88.7 × 109
Density 1922
Expansion 5.6 × 10−6
Specific heat 3000
Conductivity 3
Density, pore fluid 1000
Expansion, pore fluid 69. × 10−6
Specific heat, pore fluid 4186
Conductivity, pore fluid 0.58
Permeability 0.001
Specific weight of fluid 9800

Loading and boundary conditions

Pore pressure of 10 units and surface pressure of 2 units is applied on the top surface. The temperature at the top surface is set to 100 units. Normal displacement is constrained on three faces. Elements at the center of the block are removed and added in various steps.

Results and discussion

The models produce results that match the expected values.
