Hi Everybody,

I am an Italian mechanical engineer. It's one year I've been in the Wind energy business. I served the Fraunhofer IWES in Bremerhaven within the "Simulation and Assessment of Wind Turbines" in the periods March/June 2011 and October 2011/January 2012: I was involved in the modeling of a 3D turbulent wind field approaching the WEC. I developed in Matlab two models: the Sandia Model and the Mann model. 

Since March I hold the position of Load Calculation Engineer at Areva Wind GmbH.

Hi

I was modeled a frame @ 6 plates that this plates must be attached to the below frame by some plastic nonlinear translational spring

the specification of this springs ( force-displacement curve) is available & this propety must be define to springs in abaqus model. I can not find this spring in abaqus ,define this propery .hepl me pease to solve this problem.

thanks alot

I am getting this warning message many times " system matrix has 1 negative eigenvalues", strain increment too large, and finally stop with the error "Too many attempts made for this increment.

I modelled a Steel Barge(front part of ship) with shell elements and it is impacted by  a rigid body. When the rigid body was given a displacement of 2.5 inches it runs. But when I increase the displacement to more than that it doesnt work. I should get the Force displacement behaviour of barge by impacting this rigid pier in to it at least 20-40inch.

hi hi

how can i print this results in abaqus explicit ?????????

1-load deflection curve

2- impact load with time

my model is reinforced column hit by rigid body by giving it velocity and weight , and i cant know text use in (inp) file to print this results
