linking abaqus & matlab by python

 

Hi all Dears,
I wrote a python script which read abaqus odb file and save it in dat file format to be useful in optimization process in matlab.
 But I don't know how to update odb file in python! in other word, in every iteration in matlab, a new odb file is generated and I dont know how to insert it in python script automatically? can any one help me?
Thank you in advance

Re: Using Coupled Eulerian Lagrangian

 

You can model elastic materials in cel domain but the availability of the analysis depends on its physics.

[image: CEL figure.png]Hi all,

Before actually using CEL to model my analysis, I wanted to ask if anyone
has done similar analysis? I am trying to impact an elastic part on a
plastic part at high strain rates (10^5 /s). My question is, can elastic
part be modeled using CEL? Will field output show the stress evolution
within the elastic part? I have included the model in the figure. The
lagrangian parts will superimpose over the eulerian part during assembly.
Hope I am clear with my question.

Regards,
Rohan

Re: How to calculate heat accumulation

 

Hello Deepak,

means you can calculate the sum over all time increments sum over all elements with the product of element volume, element density, heat capacity(T) and temperature difference to the previous time increment.

I would cross check with the output of the variable HTLA on the surfaces:

HFL Heat flux per unit area leaving the slave surface.
HFLA HFL multiplied by the nodal area.
HTLA Time integrated HFLA.


Regards. Andre

Hi,

Thanks for the reply !!

For the sake of more clarity, in my work the heat enters into a domain through one of its edges by virtue of a temperature gradient between the domain boundary and outside environment. I am implementing the Abaqus transient analysis. It goes on until the body saturates (ie domain temp. becomes equal to environment temperature). Let's say it takes t secs. to saturate. The domain has some volume (V). The heat once enters gets embodied and it can not leave the body (Assume all the sealed boundaries except one from which heat is entering). I would like to calculate the embodied heat energy in complete volume during this time period.

Regards,
Deepak Jain

Please define "heat accumulation during the given time period".
Sum or difference of which physical quantity?

In my world heat is what is written in wikipedia: the energy transferred between thermodynamic systems.

Error using getArea()

 

Dear Abaqus Experts,


I would appreciate your help with the following.


I am trying to determine the total area of an element surface set, and according to the reference manual, the getArea() command is appropriate. However, I am new to python scripting and I tried the following commands in the Abaqus/CAE kernel command line interface, unsuccessfully;


>>> import part

>>> prt = mdb.models['Model-1'].parts['RADIUS']

>>> fcs = mdb.models['Model-1'].parts['RADIUS'].surfaces['R_bic_surf'].faces

>>> prt.getArea(fcs)

Specified GeomSequence is empty.


Any suggestions to get this to work would be much appreciated.

Thank you for your time,


Joshua

Pressure Difference Calculation

 

Hi everyone, 

I am working on ABAQUS to simulate Pipeline Inspection Gauge (PIG) movement in a pipeline via CEL technique. I am unable to find how to calculate Pressure Difference in the pipeline using Abaqus.

If anyone of you can guide me through it.

Open-channel flow with a sluice gate

 

Hi! I am dealing with a problem that consists on an open-channel flow with a sluice gate. The sluice gate it's well submerged (the water depth difference is relative small between upstream and downstream of the sluice gate). I´ve been searching the Abaqus documentation in order to find an similar example to this problem but i haven´t found such thing. I need some help modelling the water-air interface, any advice would be appreciate.


Thanks!

P.S. Sorry for my bad english!

Change spring stiffness during restart analysis. It is possible?

 

Hello everyone,

I want to conduct a restart analysis with abaqus, where at each restart step
I want to change the stiffness of a spring. The problem is that always
abaqus restart the analysis using the initial input file, which I can not
manage to update it.

Does anyone can help me on this?

Thank you in advance,
Skalko
