Hello,

I have a 6mm straight tube which is pressureized to 8bar dry air, then the pressure is 

released to 2 bar and the time is measured. (pressure drop duration)

I wonder if this problem is possible to analyize in Abaqus CFD?

In abaqus CFD i can assign 8 bar pressure at one end of the tube and 2 bar at

the other end but then i wonder if Abaqus will adjust the velocity to achieve this 

solution during the specified step time, if this is the case then i will not

be able to get the correct time?

Recently I submitted an article in an ASME journal and the associate editor accepted. But, the Editor-in-Chief rejected it.

Do anyone of you has any such experience?

Hi Everyone,

Has anyone been able to successfully code a UEL for modelling multiphase flow in rocks in abaqus, I have seen some work by Björn Schümann and checked out some of his references (Holler, 2006) but i have been unable to get this to work. Any ideas or can anyone point me in the right direction ?

Thanks

How to model hydrostatic pressure on a block (using ρhg fomula)in eulerian part of abaqus software

I use the 2D axisymmetric model to build a surface-based fluid cavity in Abaqus/standard. The model is showed in the attached picture. The fluid cavity surface is the arc and the refenrence point is the center of the arc.

When I complete the calculation case, it came the following warning messege:

WARNING: "The surface assembly_al-1_surf-pore is not completely enclosed. A list of element with free edges on this surface is given as follows:"

but the history output value CVOL (hydrostatic fluid cavity volume) is right, which is equel to the whole sphere.

Hello,

not able to edit ABAQUS/CFD 6.10 input file

the keyword for an abaqus/cfd model cannot be edited

???? any suggestion???

WHILE I AM PERFORMING CO-SIMULATION

Hey, everyone.

Is there anyone familiar with the Generalized Fluid System Simulation Program (GFSSP)? It is a powerful tool developed by NASA Marshall Space Flight Center. I am an engineer on gas turbine. I developed a similar but more simplified, and light-weighted tool, by C programming language.
