History output from the file created with CAE

Submitted by ABAqirl on
research

Hello everybody,

I am looking for experts in ABAQUS CAE software. Its complex object-oriented structure make me confused. As it is known that history output requires  node sets, but this node sets are defined inside the instances. In order that the program understand which node sets is required one should mentioned then PART1-1.Instance. nodeset. But ABAQUS gives mistake. Experts,please explain me how it works.

 

Best regards

Hi Abaqus experts



I am hoping that you can help me getting a element user subroutine writen in fortran f90 to work in Abaqus. I have made the simplest 8 noded brick element element that i can think of. I has a zero thickness and only has some simple definitions of the parameters ESTIFF,RHS,SVARS and PNEWDT. I have made a model with one single element of this user element where the upper part is displaced from the lower part which are fixed.



When I try to run the model I get the following message in the log file:

Micromechanics in geotechnical engineering

Hi all,

What is the prerequisite knowledge required for research in micromechanics, I did my masters in geotechnical engineering and thinking to continue Ph.D in micromechnics ( granular media).

As I am from geotechnical (Soil) Background, can anybody please inform me the prerequisite knowledge required like what course should I take, what software skills are needed to learn e.t.c.

Thank You in Advance

Hi friends,

can you help me in modellingComposite Column using steel and Concrete.

I am using Concrete Damage Plasticity material model for concrete.

I collected parameters from literatures and i tried to implement it into abaqus.

But I am not able to solve this problem.

Abaqus ends the problem with error 

 

Thanks in advance

Dear All,

Because i am absolutely new in ABAQUS CAE, i have some problem.

I have created my first model with ABAQUS CAE and the problem which i force,- i don't see the option where i should put the time , So my simulations have only one point. Have anybody has the same problem.

You kind help will be highly appreciated.

problem using crystal plasticity model in Abaqus via UMAT

Crystal plasticity

I am trying to model polycrystal behaviour using Abaqus Umat via crytalplasticity . My Umat results for single crystal & about 5 grain, are reasonable, but when, I try to use more than 5 grain in each integration point  (polycrystal model) abaqus aborted with following message after about 15 increment:

Abaqus Error: The executable C:\SIMULIA\Abaqus\6.10-1\exec\standard.exe aborted with system error code 693...

 

I will be happy if someone guide me about this problem.
