Hi,
I have a shell element model of a wind turbine blade in Abaqus. The company I'm doing the work for uses an in house mesh generator to build the model from information about the exterior surface of the blade and the lay ups, which I believe interfaces with PATRAN. I'm using Abaqus/CAE, so I'm not sure if I'm meeting issues because of this or not. They gave me the .inp file, and I intend to use it for a composite fatigue analysis. The software I'm using requires the .odb to contain the individual lamina stresses in the local coordinate system for each layer in each individual element.
I've pasted info about the model below:
Total number of nodes: 28077
Total number of elements: 27698
17 linear line elements of type B31
22000 linear quadrilateral elements of type S4R
3803 linear quadrilateral elements of type S4
573 linear triangular elements of type S3R
1305 linear hexahedral elements of type SC8R
Under sections in the model tree, there are 3699 different composite lay ups defined. In assembly->sets there are 7933 different element sets defined; my guess is that these correspond to individual layers of laminate that must be laid up at the manufacturing stage (at least that's what it looks like when you select a set and it highlights it in the viewport).
So, it's a big model. As I stated before, the post processor I want to use requires outputs from every lamina in the local laminate coordinate system. So, in field output requests I see a choice of domain (which allows me to use the whole model, or one of the 7933 sets. No composite lay ups are defined in the model). I'll have to use the whole model as I don't have time to go through every set, look up how many layers it has and then specify the outputs. My question is this: is there something I can type in the 'specify' box of 'outputs at beam, shell and layered section points' that will output every available layer at every available point? I can't find anything in the documentation.
Thanks in advance for any light you can shed on this!
