Dear all,

I have successfully run my Job in Abaqus, in .dat file I have Eingenvalue data and other. I need also the Eigenvector data. In which file can I find it?   

Hi everybody,

I have 6 desktop computers with the following specifications (all of them are the same):

CPU: 2 GHz, 2 cores, 8 Hyper Threading

RAM: 12 Gb

HDD: 500 Gb

Windows 7 (which I need to change to Windows Server with HPC pack)

I need to connect them together and make a cluster for abaqus analysis. I'm thinking about using Microsoft HPC pack since it seems to be an easy and user friendly option (I don't have any experience in that area).

Dear all,

I want to implement Dr Huang's code for polycrystals. I am stuck at two issues. 

1. How do we define the orientation to each grain separately in the code ? (I believe we need to do it in texture.txti ?)  I am not able to understand the texture.txti file.

2. What else would be different for a polycrystal CP umat implementation?

I apologize if my doubts are too basic. Please assist.

what is boundary condition that should be applied to let rectangular plate to be curved in longitude direction for rolling plate

how to change a result file to ASCII format? 

I was studying r .hill paper ....does any body have an idea from where do these equations came from??????

Please see the equations in link below

Hi All,

I am new abaqus user and i do a parametrics study by abqus python script. I try to find the nearest node from specific one has (x,y,z) then select it and apply a displacement for this nearest one by python scrpit. I hope anyone can help me and thx for all.

Hi everyone,

My VUMAT works well in 1 or 4 element tests in explicit, but behave odd (displacement continuing to increase though load was kept constant) when larger number of elements are applied. Is there anyone know the reason of the odd phenonmenon? Thanks.

It works well for tests in implicit no matter how many elements are applied.

Hi everyone, I'm making a research related to spur gear.

Basically the model consist in two gears. My problem is that they did not rotate doesn't matter what I make. So far my model is defined:

Contact-> Frictionless -> Augmented Lagrange

                Two revolute joints defined with the internal face of the gears. 

Applied moment on one joint, and revolutions in the other one. (I also tried just putting the moment and leave the other one without any rotation).

1. Justify if a stick of different length (same mass) is easier to be balanced with your hand with longer or shorter lengths. Calculation of inertia. Justify with calculations.

2. Definition of DOF and calculate them for a basic suspension, like double wishbone. Identify all the joints used.
