define water in abaqus

You can define CLOSED water in ABAQUS.

Dear ronoren24,

I dont know what you exactly want to simulate, but you might want to take a look at the following paper.

"A numerical study of the effect of loading conditions on tubular hydroforming" Journal of Materials Processing Technology, Volume 196, Issues 1-3,
21 January 2008,
Pages 174-183 

In this paper, I simulated tube forming with pressurized fluid with "fluid elements" available in ABAQUS. In the "modeling aspects" section, I believe I explained the modeling procedure with these special elements, and it may be helpful to you.

Good luck.

You can use Us-Up equation of state. There are numerous examples in Abaqus tutorials about this.

You can use Eulerian elements for water and Lagrangian elements for solid. It is called “Coupled Eulerian Lagrangian Method” in ABAQUS. You can find some simple example to follow in the manual. Good Luck!

Hi

        You can define water using ABAQUS. But what you want to analyse? That is what on the problem or modeling depends on.....First mesh the required thing. What shape you want pool to be? Decide the shape first. Then decide depending on the shape of the pool whether to go for 3D analysis or 2D analysis. If the pool is symmetric in shape then 2D analysis will do. Depending on what analysis you want to do, you have to choose the elements for walls of the pool. Now mesh the water, if pool is cubical in shape It will be easy to mesh the water too. I think the free surface of water will be important in meshing. Take 8 noded cubical elements for lower elements incase of 3D analysis or 4 noded rectangular element in case 2D. As free surface is crutial for the analysis take 20 noded cubical elements in case of 3D and 8 noded rectangular elements in case of 2D. Now, we have two geometries. One for walls of the pool and other for water. Next is you have to assign the material properties. For second geometry assign liquid density etc. After assigning the properties....You have to join both the geometries...........I feel joining these two geometris is very crutial and it also depends on what  your analysis is?

Inspiration and genius--one and the same.

Dear ronoren24,

I am new to ABAQUS as well !!

I am trying to simulate fluid-solid interaction of turbine blades in ABAQUS. I am finding difficult to simulate the flow of water in Abaqus.

If you have any i/p file related to "simulating folw of water", could you please send it to my mail id : deepak.h25@gmail.com

Hi,

I am also attempting a similar problem to the one stated above. I am modelling a 3D enclosed hollow cylinder made out of a kapton membrane. This cylinder will be subjected to hydrostatic pressure from one side to the other side. I am modelling this simulation in abaqus and i am attempting to do a  dynamic explicit analysis. I was informed that i would have to modify the input file in order to apply a hydrostatic pressure in abaqus explicit as there is no option in the interactive method. But i am unsure on how to modify this input file to apply this pressure.

Any suggestions on this topic will be much appreciated as i have appreared to reach a dead end.

Thanks for your time and patience

Hi

I want to simulate water in crack in rock can you help me?

Dear all;

I'm trying to simulate saturated soil under dynamic loading. I found that the analysis must be done by using (Dynamic Implicit). But the output gave no results for the Pore pressure-time history. I think the couple analysis doesn't work. Please advice me.
