ABAQUS 模拟杆中水的运动 简要的步骤介绍和笔记

结果【.gif-等待加载】

step1 Create the eulerian part

• use the bigger eulerian part to cover the water inside.

step2 Define the material

• define the material of eulerian part

DO NOT give half-water material

• Don’t worry about the warning about without material when submitting

step3 Create the discrete Field

• Choose the bigger eulerian part the then the half-water to define the discrete Field

step4 Define the general contact

• Just define it, without the detail property

step5 Define the Load

• Define the predefined field and choose the discrete field created.

Result discussion and future improve

• Compare the result with the bar without water inside, we can see the bar’s movement direction changes backward and forward due to the inertia of water movement.
• The stress wave propagation is also quite different.
