Abaqus crashes when writing field output report from file

 

  Hi all,

I'm trying to write a script to do some post-processing for me, but every time I ask the script to write a field report, it crashes and gives me the following warning:



Searching through google and the Abaqus resources has been zero help trying to resolve this. The line that's breaking should be

session.writeFieldReport(fileName = JOBNAME, append = OFF, odb = ODBE, sortItem = 'Node Label', step=0, frame=0, outputPosition = NODAL, variable = (('COORD', NODAL, ((COMPONENT, 'COOR2'), (COMPONENT, 'COOR1'), )), ), displayGroup=dg)
I can open viewer and manually write the report perfectly fine, but as soon as I try and use a script it breaks. I have no idea what's going on, and any help would be appreciated. Thanks a bunch!

Material models for Composite in ABAQUS

 

Hello,

I am curious about how many inbuilt material models are available for modeling failure in composites?
Is it the "Hashin" model that is the only ready made available? or are there any others as well?

Regards
Moeen

Solid/liquid interface

 

Hi all,


     I'm trying to model surface melting and solidification problem due to constant flux at the surface. Can anyone please suggest me how to calculate the solid/liquid interface location as a function of time? Any guidelines will be appreciated. 


Thanks

Shams

Help meshing a complex part

 

Hi all,


I'm meshing a lattice like solid structure but having nightmare meshing it. Would any kind hearted person have a look at it and help me mesh it? Automatic mesh is not possible, so I used Tet elements but elements are distorted. So best is to get Hex (C3D8) elements.


The cae file (Version 6.14) is here - Mesh_problem.cae



Thanks!

how to apply a shear strain e12 in abaqus for periodic boundary condition

 

hi

i wonder how i can apply a shear strain e12 on a node in abaqus!

can it be done by rotation boundary condition? and

could any one please tell me how to apply periodic boundary conditions for off axis loading on unidirectional fiber composite.

I am trying to apply the PBC according to this paper "Yunfa Zhang ,Zihui Xia,Micromechanical Analysis of Interphase Damage for Fiber Reinforced Composite
Laminates", but the model does not seam right.

Could any one please tell me the steps that I shall take.

Do i have to use a user subroutine?


Thanks

Non convergence for micron scaled model.

 

Hi Everybody,
I am using a micron scaled model for polymer.However I have had to scale the density of the polymer 1e6 times to get results. My polymer has a density of 2000 kg/m3. Hence in the micron scale the density in ton kg/um3should be 2e-18 . However I have had to use 2e-12 to get any output. Using very low values results in my model not completing the execution . Simulation is not able to progress with the time increment. It may be a case of non convergence. 
My polymer Youngs modulus is 50 MPa or 50e-6 N/um2Traction stress  = 1 MPa or 1e-6 N/um2Steel Youngs modulus is 210 GPa or 0.21 N/um2.Speed = 165 um/s.
I have attached my inp file along if anybody could let me know what may be the reason for the problem.
thank youShouvik Ganguly

Re: Boundary conditions Abaqus

 

Hello,

I am sorry for disturbing you again, i want to use the option of equation
constraint to do the periodicity in my kelvin cell, equations should be:

1)Ui1 - Ui2 = Ui1(ref) - Ui2(ref) with i=1,2,3 (Uij(ref) are displacements
of conjuguate points)
2)Oi1 - Oi2 = 0 with i=1,2,3 (O is theta the rotation)

but how can i introduce these equations in the equation constraints in
Abaqus? can u tell me the steps i should do? (i've seen this part in the
abaqus tutorial but still don't know how to do it)

thank you in advance

sarah

Python scripting interface: How to write surface node field output?

 

Hello,

I’m using Abaqus’ Python scripting interface and am currently trying to write
field output for a surface quantity.

The surface fields generated by Abaqus, p. e. CSHEAR1, show the following
structure:

In the fieldOutputs repository they are referenced seperately for every pair
of surfaces for which they exist, p. e.

CSHEAR1 Face_1/Face_2
CSHEAR1 Face_3/Face_4

The field output objects behind these are all the same, containing the data
for all contact pairs and bearing the Name CSHEAR1.

Now I can create a new FieldOutput object and use addData to generate a field
apparently identical to CSHEAR1. It appears identically as far as a query of
the field output object is concerned. But in the GUI my field output behaves
as a volume quantity field, it is declared as existing “at nodes”—while CSHEAR
is declared as existing “at surface nodes”—and it is visualised accordingly.

I’d like to know:

Which data structure of the Abaqus’ python object model shows the relation of
a field output quantity to the surfaces to which it belongs?

How can these properties be written?

So far the Abaqus Scripting User’s Guide and the Abaqus Scripting Reference
Guide haven’t helped me in this. Any hints would be appreciated.
