Benchmark

Due to the complexity of the description of the multiphase system soil, verification of software for geotechnical problems is not possible or only possible to a limited extent. Therefore, we demonstrate the applicability and correctness of our implemented methods (both known and newly developed) by a combination of verification by means of abstract (possibly unrealistic) boundary value problems for which analytical solutions exist and validation by recalculation of experiments or results of numerical investigations with other FE programs such as Plaxis or Abaqus.
