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:

Statenew(k,2)=Stateold(k,2)*10

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.

UMAT subroutine for 3d solid elements

Dear All,
I am okay in ABAQUS although trying subroutines for the first time.
I am trying to modify some codes available online, but the primary UMAT which I am posting here, is not working.
It shows no error in .log file but the job monitor says "Problem during compilation - D:\Abaqus Work Directory\Trial_user_subroutine\try\Umat_mine.for"

Please help me this, its very urgent.
Thanking you all,
P.S. The code is attached in .txt format
Here is the code

Postdoc position: Phase field models for inelastic deformations in materials

A Postdoctoral position will likely be available at The Johns Hopkins University, Baltimore, U.S.A. in the area of phase field modeling of inelastic deformations, including fracture, under extreme thermomechanical loading conditions. The potential candidate should have a Ph.D. in engineering or physical sciences disciplines, background in numerical methods, intensive experience related to a topic in multiscale simulations of materials.

PhD Position in Arterial Biomechanics and MR Imaging in Trinity College Dublin

The aim of the research project is to develop a means of identifying alterations in collagen fibre architecture of arteries in vivo using non-invasive imaging techniques that can be linked with disease progression. DT-MRI has been used to characterise fibre patterns in animal tissue and this project will explore the means by which this can be enhanced in human tissue. Potential applications of the NODDI (neurite orientation dispersion and density imaging) protocol in arterial tissue will be explored.

Define Density

Dear All,

I do not know how to see the density (or any other arbitrary variables) contours as the result of my process. Should I define any special things? should I write any code?...

 

Any helps would be highly appreciated.

Career perspectives in the field of "porous media"

Hi everyone,

 

 I was wondering what the career opportunities would look like after getting a PhD in numerical simulation of porous media. Besides a research job in universities, what other possibilities are there? Would industry also be interested in such specialization and if yes in which sectors?

 

Thank you for your opinions.

Call for Abstracts _TMS 2016: Additive Forming of Components - Tailoring Specific Material Properties in Low Volume Production

Advancements in additive manufacturing technology have created the ability to design and construct parts with geometries and properties that cannot be achieved through traditional machining processes. This ability has promoted new design strategies whose success relies on close integration of engineering with materials science. Of particular interest is tailoring specific material properties in low-volume production.
