Tutorials
This section introduces numgeo through a sequence of hands-on examples, progressing from elementary element tests to realistic boundary-value problems and, finally, user-defined extensions. Each tutorial is self-contained and can be completed independently.
- Element test simulations: The first steps - you'll learn about the numgeo input file format and structure, basic keywords and special features for the simulation of geotechnical lab tests.
- Strip footing: The first step towards the simulation of more complex boundary value problems. Learn how to create models with more than one body and formulate contact between the two.
- Unsaturated flow: Some examples gently introducing you to the simulation of flow in unsaturated soils
Element test simulations
Example of using numgeo for the back-calculation of the laboratory tests with different advanced constitutive models. How the individual tests are exactly simulated is described in detail in the following sections.
-
Oedometer test
Single element simulation of an oedometric compression test with the Hypo-ISA model
-
Triaxial test: CD
Single element simulation of a drained monotonic triaxial test test with the Hypo-ISA model
-
Triaxial test: CU
Single element simulation of an undrained monotonic triaxial test test with the Hypo-ISA model
-
Triaxial test: cyclic CU
Single element simulation of a cyclic undrained triaxial test with the Hypo-ISA model
-
Triaxial test: high-cyclic CD
Single element simulation of a high-cyclic drained triaxial test with the HCA model
-
Triaxial test: high-cyclic CU
Single element simulation of a high-cyclic undrained triaxial test with the HCA model
