2024年12月20日、張 浩 教授（大学院先端科学研究部）が世話人による第139回IROASTセミナーに、ケンブリッジ大学所属のDongfang LIANG教授（IROAST客員教授）をお迎えしました。
Liang先生は今年度よりIROAST客員准教授に就任しており、今回、「IROAST招へい支援事業」のサポートで来日されました。

今回のセミナーでは、「海洋波、地すべり、土壌と水の相互作用のメッシュフリーモデリング」と題し、水に関する基礎理論と数値解析方法の観点から講義をされました。
講義の最初には、ケンブリッジ大学の紹介もされ、歴史のある名門の大学の様子に、参加した学生たちにとっていい刺激となったようです。

On December 20, 2024, we welcomed Prof. Dongfang LIANG (IROAST Visiting Professor), the University of Cambridge, to the 139th IROAST Seminar, which was organized by Prof. Hiroshi CHO ( Faculty of Advanced Sciences and Technology).
Prof. Liang has been a visiting associate professor at IROAST since this fiscal year and came to Japan this time with the support of the “IROAST Invitation Support Program".

In this seminar titled "Meshfree Modelling of Ocean Waves, Landslides and Soil-Water Interactions" he gave a lecture from the viewpoints of basic theories and numerical methods related to water.
At the beginning of the lecture, the University of Cambridge was introduced, and it seemed to be a good stimulus for the participating students to learn about the prestigious university with a long history.

3．講演者・演題 (Speaker & Title)：

   Prof.Dongfang LIANG, University of Cambridge, UK
 “Meshfree Modelling of Ocean Waves, Landslides and Soil-Water Interactions”

4．概要 (Abstract) ：
Traditionally, the numerical solution of continuum mechanics problems requires the decomposition of the domain with computational mesh. Once the domain boundary changes, the mesh should be updated to adapt to the new boundary. This talk will show several examples of applying the modern meshfree computational methods to civil engineering problems involving large deformations at the boundary, such as nonlinear ocean waves, sediment transport and landslides. The meshfree methods are ideal for this type of problems, because they inherently avoid the mesh distortion. In civil engineering, the strong interactions between soil and water are often crucial in the phenomena like the seepage induced slope instability and wave runup on porous beaches. The necessity of considering the dynamic coupling between the soil and water phases will be explained as well as the importance of satisfying both the mass and momentum conservation principles. The meshfree methods included in this talk are the Smoothed Particle Hydrodynamics (SPH) and Material Point Method (MPM), which have been increasingly used in scientific computing.
