"keyword *CO-SIMULATIONREGION is misplaced" Error

Choose a channel featured in the header of iMechanica: 

i everyone,

I am UG student of Mechanical Engineering. I am a new user of Abaqus and currently working on co-simulation for my final year  project. Actually what I am doing is prediction of heat transfer due to fluid flow in a tube of known diameter across which air is flowing, also called as conjugate heat transfer.

I created model in Abaqus/standard named Tube, created part as Tube

How to assign orientation for fibers in woven composite ?

Hello everyone,
 
I am working on textile composites. I have to assign local material orientation for the fibers. I have come across *ORIENT  subroutine in abaqus. But I am quite new to user subroutines. Is there any other way in which I can assign local material orientation to the fibers?
The fiber layout is such  that it has linear as well as sine part. Can anyone give some idea on how to create *ORIENT for such fibers?

Urgent help - Contact modelling in Abaqus

Dear all
I urgently need the answer to my question. I am modelling a clapping or contact between two surfaces similar to a crack.
I have used abaqus : 1-tangential : frictionless  2-Hard contact
I wanna know what moelling approach does abaqus use for above situation ?
Does abaqsu use hertzian contac ? bilinear stiffness or what ?
Thank you

Why the VVF of GTN model within Abaqus keeps 0

I calculated an example of unaxial tension using GTN model offered by Abaqus. I followed all the instructions found in CAE User's and Analysis User's manual in Abaqus documentation. No error or warning was issued but the result seemed ridiculous, since VVF, VVFG and VVFN keeped 0 throughout the process while equivalent plastic strain keeped increasing(which showed the material had come into plastic deformation). I don't know what went wrong, looking forward to you reply.

Ice failure simulation

Hi,

  I want to simulate Ice failure simulation in abaqus. In my problem, ice is deposited between 2 components.

  While I am trying to move one compoents, the ice is restricting the movement of the components. Now I want to find out the force at which the ice starts to failure .

  any methods are available n abaqus., Plz let me know if any body knows abt this kind of simulation.

 

Thanks in advance

Abaqus: Composite delamination with cohesive elements

 

Hello,

I have to do a FEA regarding impact damage and delamination propagation in a CFRP specimen.

I have to do this using cohesive element in order to see the propagation of the delamination front in the material.

My problem is that I don't know how to do this in Abaqus.

I'll better explain: I can use this software but is the first time approching composite behavior and I really don't know how to model that.

Abaqus Max Principal vs Max Principal (Abs) values

Hi every one,

                   Does Any one know the difference between Max. Principal values and Max.Principal(Abs) values in Abaqus ? I searched from there manual..but they have not mentioned in there manual too..could you please let me know the difference between those two parameters? Thank you very much.

Nodal stress and strain history output from Abaqus

Hi everyone,

I am trying to get the history output of
strain and stress tensor components at a node. However after analysis is
finished no such data are saved in the result section. I think Abaqus
only gives the stress and strain for elements and not at nodes. Any help
would be highly appreciated. Please consider that I am a new abaqus
use.

Thank you in advance

Modeling associative Tresca plasticity in ABAQUS?

Hi

I have a simple question. How could I model associative Tresca plasticity in ABAQUS?

 I use Property module: material editor: Mechanical:Plasticity:Mohr Coulomb Plasticity

I know that In the case (friction angle=0) of  the Mohr-Coulomb model reduces to the pressure-independent Tresca model with a perfectly hexagonal deviatoric section. 

Applying Periodic Boundary Conditions(PBC) in Abaqus

Hi all,

     I am looking for some reference on procedures for applying  PBC in  abaqus? I coud find some journal articles for the equation, but I am unaware of applying this into Abaqus under displacement laoding conditions..

any help in this regard would be appreciated greatly..

 

Thanks,
