One focus of B06 is the application of the numerical schemes from the first funding period to experiments of the CRC, especially those with phase transitions. By connecting the inhouse Extended Discontinuous Galerkin (XDG) code to the OpenFOAM infrastructure, the DG method can be applied within other CRC pro-jects, e.g. to phase field models in cooperation with B07N. The second focus is the continuation of contact line modelling with the XDG method. Due to its high local accuracy, this method is particularly suitable for the investigation of thermodynamic inconsistencies of contact line models. Moreover, singularities of the flow fields can be treated by means of local basis functions.

B06 的一个重点是将第一个资助期的数值方案应用于 CRC 实验，特别是那些具有相变的实验。通过将内部扩展不连续 Galerkin (XDG) 代码连接到 OpenFOAM 基础设施，DG 方法可以应用于其他 CRC 项目，例如与 B07N 合作建立相场模型。第二个重点是使用 XDG 方法继续进行接触线建模。由于其局部精度高，该方法特别适合研究接触线模型的热力学不一致性。此外，流场的奇点可以通过局部基函数来处理。
