Need help in executing ANSYS subroutine userpr

Dear all

I need help in executing ANSYS user programmable feature (UPF), specifically subroutine userpr (changing element pressure information) for my 2D model. I have read the manual but don't understand the subroutine program structure (attached below). Can someone kindly explain how can I activate and run the subroutine?

Thanks,

Samuel

Geotechnical engineering

Two PhD scholarships, funded by the Spanish Ministry of Science, are currently available in the Department of Geotechnical Engineering and Geosciences at Universitat Politècnica de Catalunya (UPC) (Barcelona, Spain). The PhD positions are associated to the Project “Progressive failure and the reactivation of big landslides: Analysis, prediction and risks (BIG RISK)” with Professor Eduardo Alonso and Professor Jordi Corominas as principal researchers.

Memories of IT. Part 2

Submitted by Zhigang Suo on

Looking back at episodes of our lives, we reflect on how people meet and how such meetings change lives.  Information technology, broadly interpreted as means of communication among people, is always part of these narratives.  But central to such narratives are nearly always people themselves and the content of their communication, rather than the means of their communication. 

Is there a failure criterion/model for brittle spheres?

Submitted by shuo zhao on

failure model

Hi, everyone

I am a student. I am  dealing with a failure problem of brittle spheres. These have a lot of flaws inside.I did some compression tests. Single spheres are crushed by a pair of parallel plates. I got the crush load distribution (in terms of critical contact force). 

My question is:

is there a failure criterion/model which relates to load(critical contact force), Youngs moduli and Poisson ratios of shpere and plates, radius and friction coefficient?

Coupling Abaqus with an aeroedynamic BEM code to compute aeroelastic respons

Fluid-Structure Coupling

For my graduation work (student at the Delft university of Technology, The Netherlands), I am trying to model the aeroelastic behavior of a wind turbine rotor. For this end I use an Abaqus model of a wind turbine blade (which is a composite structure with different fiber layers and corresponding orientation). The aerodynamic force is calculated by a BEM code (Blade Element Momentum theory), which is a simplified engineering aerodynamic code: fast but still quite good. Using CFD to calculate the loads is out of the question since it requires far too much time to calculate.
