PhD and post-doctoral positions on multiscale materials modeling at IMDEA Materials Institute

Two PhD and two post-doctoral positions are available at IMDEA Materials Institute within the framework of a project funded by the European Reseach Council to develop multiscale modeling strategies –together with the corresponding experimental validation– to simulate the microstructural development during solidification and thermal treatments as well as the mechanical behavior at different length scales of Al and Mg alloys.

More details and information to apply can be found in the enclosed files.

Subroutine DFLUX in ABAQUS

Dear Mechanicians,

time and again the question of modeling moving heat sources pops up, often in the context of laser heating.

One can achieve this using the subroutine DFLUX in ABAQUS.

I decided to post some links here to avoid responding with a longer explanation to every individual seeking assistance.

Please note that I have never worked with any one of these codes and have no access to ABAQUS at present.

No warranty is given by me.

About Dstran or Stran of cohesive element in ABAQUS

  I want to ask you a question,
  I debug a constitutive model about the cohesive element in ABAQUS.
  You know the key point of this element's constitutive model is Traction-Seperation Relationship.
  I want to test my model by Umat, not the Uel.
  So I want to ask whether Stran is the relative displacement(not strain) of the Gauss point in this type element.
  And how Dstran is calculated by UEL subroutine!!!

Abaqus, DFLUX subroutine, modeling

Hi Guys,

I've got a question regarding welding simulation. I'm modeling a plate of size 180*120*17mm and a moving heat source using Abaqus and DFLUX subroutine.
Therefore, I wrote the input file, define the properties, loads, convection and radiation, etc. I also wrote a FORTRAN code -DFLUX- for moving heat source.

S23=0 as a boundary condition in static step


I need help in setting the s23 on a certain surface in my model to be zero. But the following pops up:
"loads must be created with a non zero magnitudes unless utilizing a user subroutine"

what subroutine shall I use and how?

abaqus multi scale modeling


I'm a beginner in abaqus and I started to simulate an multiscale analysis, I model both micro and macro scales and even homogenization part for micro scale outputs, but I couldn't perform a relation between two scales. i know the parts of the code, but i can't call python from fortran subroutine.

could any expert guide me how to overcome this problem? i want to know if i can find any template or simple implementation of multi-scale modeling in abaqus?

ABAQUS built-in SMA model

Dear Mechanicians,

time and again the question of SMA (shape memory alloy) modeling pops up.

In ABAQUS, you can achieve this only by (V)UMAT coding or by using the little-known built-in SMA model.

In the past I have frequently responded to queries on SMA modeling and could refer to a customer help site of SIMULIA. That site is down, regrettably.

I decided to post the files here to avoid responding with a longer explanation to every individual seeking assistance and uploading the files as E-mail attachment every time.

i must learn to work with VUINTER and VUINTERACTION subroutines.plz help me...

is there any body who knows how to work with these codes??

best wishes

Manipulation of SDV in VUSDFLD subroutines

I am trying to write a subroutine with VUSDFLD

I would like to manipulate the Solution Dependent Variables based on its previous value as follows:


But Multiplaction and Divisiion operations do not give any results. They give 'No value' when they are output.

Would anyone know why this happens?


Thank you.

Conversion of gemotry in beam section

Dear all,

In ANSYS mechanical I am interested for free vibration analysis of ship structure, for it I have an weight distribution information along with all geometry details . I am looking for frequency as a an output from it. 

I want to convert the ship into equivalent beam section ,anyone has an Idea how to convert it into beam element ?

As per my knowledge I have to take care of CG location ,Ixx ,Iyy and Izz.

Kindly help me to perform same.
