ABAQUS

I am modelling an inflated sphere. The sphere is composed off two circular planar membranes joined together at the boundries. 

I have modelled the inside of the sphere as a fluid cavity and will inflate it to its threshold limit. 



I have achieved this by using the fluid cavity and fluid inflator method but for some reason when I run my input file I receive the following message: 



 ***ERROR: THE FLUID INFLATOR ACTIVATION HAS BEEN SPECIFIED ON THE FLUID 

The latest issue of SIMULIA Community News takes a look at how engineers in the industrial equipment industry are using realistic simulation solutions to optimize performance, evaluate designs, and further their understanding of the environments they work in. Additionally, see how Mazda balances performance and weight in a steel car body and NSE Composites validates their sweep-twist wind turbine blade design that captures 12% more energy.



We hope you enjoy this issue of SIMULIA Community News .

Hi colleage

I am modelling a Piezo Beam 2D and 3D, i have no problem with 3D when i want to apply voltage load, But in 2D, when i apply load i Dont get any results in case of stress and strain Also when i apply pressure to beam, i Must get Voltage in Piezo but nothing happend, PLEASE HELP ME IN THIS CASE; THANKS ALOT 

I'm using Abaqus in analysis of random vibration fatigue. I linked abaqus with fe-safe to calculate the fatigue life. Fe-safe didn't recognize the random load comming from Abaqus correctly, althghou it already recognize the cyclic(normal) load crrectly in one of the tutorial's attached example.

Do any body know how to solve this issue?

The reliability of a gas or steam turbine is strongly
dependent on the blade structural design. 
Turbine blades are subjected
to very strenuous environments such as high temperatures, high stresses, and a
potentially high vibration environment. To avoid blade failures, they must be
designed to withstand these conditions. 

Hi everyone,

There is a video on YouTube now of a cat using Abaqus...more specifically, the Abaqus Knee Simulator (Abaqus 6.12 release). Hope it makes you laugh:

Have a great week!

I want to start a dynamic calculation in Abaqus in which, for every node, I specify the displacements, velocities and accelerations. I know that by the *IMPORT command, I can start a calculation with a deformed mesh, and that the velocities can be defined by in the *INITIAL CONDITIONS, but how to deal with non zero user defined accelerations? Have any body did that? Is it possible with a subroutine?

Thanks for any help

I build a water inject model with COH3D8RP element, in the simulation, I can get the pore pressure value around the cohesive element, but I can't the value inside the cohesive element. the pore pressure changed around the cohesive element because of the pressure inside the cohesive element changes, however, I can't get the value of pressure inside the cohesive element.

Anyone can help, pls!

I am trying to perform simulation of Crushable Foam Plasticity model. However, I am getting convergence error

***NOTE: THE SOLUTION APPEARS TO BE DIVERGING. CONVERGENCE IS JUDGED UNLIKELY.

***ERROR: TOO MANY ATTEMPTS MADE FOR THIS INCREMENT

Can someone please help. I have attached the image of Abaqus input data.

Thanks a lot in Advance.
