## Masters and PhD Opportunity in Geotechnical Engineering at Canada

Hi!

Good Day. I am a PhD student (Geotechnical Engineering) at Memorial University, Canada. Currenlty, my supervisor (http://www.mun.ca/engineering/about/people/bipulhawlader.php) is actively looking for graduate students. If you are really interested, Please E-mail your CV @ sujan95@gmail.com by October 9, 2015.

Thanks for your time.

Regards-

Sujan Dutta.

## Strain Rate Calculation in CEL

Hi!

I am trying to calculate the strain rate in Coupled Eulerian Analysis Using ABAQUS. I want to Calculate it through Plastic strain as strain rate in vuhard is not working properly. I want to fix the strain in state variable for a time period but with analysis, it is updated automatically. Is there any options to keep strain fixed for a time period?

Any idea will be highly appreciated.

## Calling VGETVRM

Hi!

Can please help me regarding usage of VGETVRM? I am trying to get material point data of EVF in an eulerian analysis using VUSDFLD but failed. Details is below:

parameter( nrData=6 )

character*3 cData(maxblk*nrData)

dimension rData(maxblk*nrData), jData(maxblk*nrData)

do k = 1, nblock

c jStatus = 1

call vgetvrm('EVF',rdata,jData,cData,jStatus)

EVF=rdata(1)

FIELD(k,1)=EVF

stateNew(k,1)=FIELD(k,1)

## About Intergration Points in Eulerian Element (pls help)

Hi!

Good Day.

Please note that I am doing Coupled Eulerian lagrangian(CEL) Analysis using ABAQUS. In this technique, mesh is fixed and material will flow through fixed mesh.

My question is:

1.Are integration points for Eulerian elements are fixed with mesh?

2.If it is fixed, how integration point captured the material behavior (as material is moving through fixed mesh)?

Sincerely-

Sujan.

## Interaction properties in CEL (abaqus)

Hi!

Hope doing well.

I am in trouble with interaction properties in CEL? I noticed that whatever my shear stress and frictional co-efficient value is, model always take it as zero i.e. frictionless property. I did this using tangential behaviour and penalty.

But I have to model it using shear stress value.

Thank you.

Sincerely-
sujan dutta.

## Pls help regarding CoordMp

Dear all,

Pls be informed that I am using abaqus explicit to model my
pipeline that
embedded in soil. In standard, Coord 1 means x co-ordinate,
coord 2 means Y
co-ordinnate and coord 3 means Z -co-ordinate. But I can not
undestand the
meaning of CoordMP(nblock,j) in explicit. I want vertical
co-ordinates of some
elements of my model but if I put CoordMP(k,2) it shows
always a constant value
for all elements which make no sense.

Can you
please explain it(CoordMP)? It will be a great help for me.

## About Coupled Eulerian Analysis( pls help)

Hi!

Good Day.

Please note that I want to model a pipeline
which is on ground surface using CEL. I have applied the geostatic stess
only in step-01. But at the end of step-01, pipe is starting to move
upward. I do not apply any force on pipe but it seems to me that pipe
experienced some force which push it to move upward. Also, I do not
apply any gravity load for pipe.
