User subroutines in ABAQUS

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.



how to simulate fibre direction?

fibre

Hi all

 I am modeling a complex muscle with fibre reinforced. The fibre direction is not constant in this muscle. It is changing with the integration point in the model. Is there anyone who got idea on how to simulate the variable fibre directions in Abaqus?  Can user subroutine ORIENT do this?

 Many thanks,

Hello all,

I am new to this. I got a couple of good inputs from this site, so I thot I would join too. I am a PhD student in Clemson univeristy. I am using ABAQUS for my research. Let me get to the question quickly. There are two variables that you can define in a user subroutine called TOL and HTOL. What are these and how can I know more details about this. Any inputs will be appreciated.

 

Thanks
