How to create a 3D surface in Abaqus using Python script based on known node coordinates?

Submitted by Yuppie Dong on

Dear All,

Does anyone know how to create a 3D surface in Abaqus using Python script based on known nodes coordinates, and partition a block using the 3D surface? For example, I have the variable ground strategraphy profile from site investigation borehole log. Then I want to implement this ground strategraphy to the geological model to consider different soil layers? I heard people can do it using a python script. Does anyone have similar experiences? Many thanks.

problem with local coordinate system

Submitted by Intissar on

Hello,

I have imposed a BC (in a local coordinate system) at a node and also imposed a load (in the global coordinate system) at that same node. When I go to submit the job, I get the error message: "Following attributes are applied to overlapping, intersecting, or adjoining regions in differing coordinate systems:...". Does anyone know how to correct this?

Thanks

ABAQUS/CFD Results in EXODUS-II Format

Submitted by Caleb Drummer on

Hi,

I have been working on solving a coupled fluid-structure problem in ABAQUS/CFD and ABAQUS/Standard for a while now. Due to the high flexibility of the solid, I have not been able to solve the coupled problem correctly. So, to advance in my research and get some preliminary results, I am looking at solving a one-way coupled problem. (IE, I will solve the fluid problem and obtain surface tractions at various times. Then, I will apply these tractions to my solid model.)

Numerical analysis on friction pads - script analysis

Hello there. My name is Angela and I am a civil engineering student finishing my master thesis. The subject of my thesis is numerical simulation of a friction pad which is subjected to several cycles of 30 mm amplitude deformation (allowed due to the existance of slotted holes). I have to report the frictional behavior of the specimen and for that I have experimental Data. The variation of the friction coefficient can be due to wearing of the plates and, consequently, loss of preload (which was not measured experimentally) and also some strain hardening of the asperities, ... 

python script

hello!

could everyone here telle me why sometimes when i run a python script in abaqus ,it gave me all the model,i mean the cae file, except  the sketch geometry 

i got the message  "the script used to crearte this sketch must be upgraded.Alternatively use the command :mdb.models[modelname].convertAllSketches()"

Is time a 'real' time for creep analysis?

Submitted by kajalschopra on

Hi,

When i'm doing a plasticity analysis, I give the input for load against time. This 'time' is in fact not the 'real' time but a 'pseudo' time since I'm not solving mx_dot_dot + kx = F but kx = F , of course 'k' gets updated at each increment (a.k.a. time).

 

My question is, if I do a creep analysis (say using Norton Bailey law), is the time a 'real' time or still a 'pseudo' time?

 

Please can anyone help with justification of your reply?

 

Thanks a lot.
