abaqus中怎么施加一个随着深度变化的压强啊？求详细过程，最好私聊。

Question

如题所述

Answer 1

参看手册中下面这段:

Hydrostatic pressure loads on two-dimensional, three-dimensional, and axisymmetric elements in Abaqus/Standard

To define hydrostatic pressure in Abaqus/Standard, give the Z-coordinates of the zero pressure level (point a in Figure 34.4.3–5) and the level at which the hydrostatic pressure is defined (point b in Figure 34.4.3–5) in an element-based or surface-based distributed load definition. For levels above the zero pressure level, the hydrostatic pressure is zero.

In planar elements the hydrostatic head is in the Y-direction; for axisymmetric elements the Z-direction is the second coordinate.
Input File Usage: Use one of the following options to define a hydrostatic pressure load:

*DLOAD
element number or element set, HPn or HP, magnitude, Z-coordinate of point a,
Z-coordinate of point b

*DSLOAD
surface name, HP, magnitude, Z-coordinate of point a,
Z-coordinate of point b

Abaqus/CAE Usage: Use the following input to define a surface-based hydrostatic pressure load:

Load module: Create Load: choose Mechanical for the Category and Pressure for the Types for Selected Step: Distribution: Hydrostatic

Element-based hydrostatic pressure loads are not supported in Abaqus/CAE.追问

我就是想定义一个随着液体深度变化的压强，请问一下是这么选择的？下面模型图

新手实在是不知道怎么定义，还请详细指教

追答

大小栏填一个压强

这个压强就是 "参考压力高度" 处的压强。

幅值是用来体现压力随时间变化的。如果不随时间变化，就不用填。

零压力高度是压力为零的处的高度坐标。相当于水表面的坐标。

可以用子程序DLOAD，非常简单的追问

我刚接触abaqus,还不怎么会用子程序，求指导一下，
