abaqus exec\pre.exe aborted with system error code 5.

Choose a channel featured in the header of iMechanica: 

Dear all

 I encouter this problem when I utilize finner mesh,while no such error was reported if a coarse mesh was used.

Could it be a problem of my computer's memory? But which memory exactly? (physical memory or the space for storage)

 I feel the calculation has not yet fully utilized my computer's physical memory according to the task manager. 

 

So, my questions are:

1. where possibly would the problem be?

2. how can i possibly address them?

 

Thanks in advance!

 

Regards

 

How to estimate crack growth propagation using the maximum tangential stress criterion method?

Hi All  Currently I am running FE modelling using linear elastic fracture mechanics approach to estimate crack growth propagation in a web plate of box girder in an existing bridge deck. The FE model includes 3D solid element. The crack growth direction is expected to follow in a plan perpendicular to the maximum principal stress.  As I know there are many methods can be used to estimate the direction of crack during propagation. My question is about the maximum tangential stress criterion method.

need help in ansys

sir,

I need to find out kinetic energy of the element in the harmonic analyis problem of a plate.

i am using ansys command...in /post1

etable,KE,KENE

but no data is stored on the lable KE

please help and suggest some other means to do the same...or the correct method of issuing this command ..

 thanks

career as computational seismologist

Dear Mechanicians,

I have got an offer to do PhD in computational seismology in a very good university in Europe, however, I have no idea what sort of career I should expect after getting my PhD in this field. I got my BSc and MSc in mechanical engineering but have never worked in the field of geophysics and seismology. Therefore I am hesitating whether to take the offer or not.

Fraud, h-index, etc.

This is an interesting article: Fraud, the h-index and Pasternak. How do we evaluate ourselves and others, especially those not in our own fields? We may not have to find an answer as an individual researcher, but the univeristy adminstrators have to.

I am confused...

How to apply uniformly distributed load to shell element when I do nonlinear analysis of I-BEAM

 

Hi, everyone:

I am using ABAQUS to do my final dissertation:nonlinear analysis of steel members.

I want to apply UNIFORMLY DISTRIBUTED LOAD to the middle height of the web, I splited the web into top and bottom parts,but nomatter I use 'LINE LOAD' OR 'SHELL  edge LOAD' ,it does not work at all.

Thank you so much in advance, any opinion is welcome.

temperature rise in VCR & VAR

What is d significance of temperature rise in VAR & VCR, as in VCR after compression the temperature increases as a consequence of pressure rise and in VAR we heat the mixture to separate absorbent. Is it a coincidence or some logic behind it?

Discussion of fracture paper #1 - A contol volume model

This is a premiere: my first contribution to the new ESIS' blog announced in January. Why comment on papers in a scientific journal after they have passed the review process already? Not to question their quality, of course, but animating a vital virtue of science again, namely discussion. The pressure to publish has increased so much that one may doubt whether there is enough time left to read scientific papers. This impression is substantiated by my experience as a referee.

Forging process simulation

Hello friends,

I am doing My Graduation in Mechanical, right now i am on a project and want to simulate Forging cylinderical billets in order to optimise the process parameters, hence it is required to optimize the process parameters like temp., speed , stroke, material flow etc. as a function of Die design and friction. I want to simulate it in ANSYS plz help me how to go for it, because finally i want stress, strain rate, strain, material flow as the final  result.

What do we do?

Yesterday, as I was waiting for the rain to stop before I could walk home from work, a stranger accosted me in the lobby of the building.  He asked me what I did, to which I replied "Mechanics".  He mulled over the answer for a bit and asked me to be more specific, at which point I said that we were trying to design materials that could guide waves around objects.  He said "Water waves?".  I replied "All types of waves."  Clearly, common words can mean quite different things to different people.

Homogeneous beam

Dear members:

 I have some basic question:

What is a homogeneous beam? why do we use homogeneous beam ? what are the characteristics of homogeneous beams?

and Where do we use these beams? and what is beam homogenization ?

 

 

welcome to discuss problems about BEM

As we known,  boundary element method (BEM)  is a quite popular numerical  method.  But there are some problems. My research fields are computational mechanics and BEM (including fast BEM).  We can discuss these fields in this blogs. I am waiting for you! Thanks

Hi,

   Just need help to find out how to read results at intergration points in Shell Elemnts in ansys. I need 5 integration points across the thickness of my model.

Thanks in advance

Mechanical vs Rheological Properties

What are the differences between "mechanical" and "rheological" properties?

Are "mechanical" properties a subset of "rheological" properties or vice versa? Or do they merely overlap?
