Thanks for your good response, Blas. I will have into account everything you have said and try to be even more careful preparing the mesh model.
As well, with my current model, I've done yet what you say about comparing results with different mesh sizes and in fact, I guess observing...
Hi, thanks for your answers!
I think it was really a refinement mesh problem in that area. Actually, I've remeshing the gusset with a smaller element size and I've observed that both elemental centroid results and nodal results converge in similar results, so you were right when said that pic 2...
Hi, I've uploaded a pair of pictures of the problem.
In the first one I have the postprocessing only considering elemental data results. The stress distribution is smoother in the area close to the inferior corner and the maximum von misses stress is 263 MPa, what is under the Yield tensile...
I've used plate elements (quad planar in Nastran)for meshing both the tubular beam and triangular gussets.
On the other hand, I don't have pictures in this moment because it's an enterprise project and I'm at home right now. Tomorrow I will upload an image(A picture is worth a thousand words...)
no, is something much simpler. It's a kind of structure with a tubular beam reinforced in the base with a few triangular gussets. The thing is that if I consider "corner data" in postprocessing the stress is much higher in some corner gussets than if I don't consider them, but only in a very...
Hi rb1957, the answer to your question is yes. As well I've tried to be very careful with this model, trying to get quad maped meshes of quality in every component. The real thing is that I'm a bit surprised with some results because of the great differences in some areas between elemental data...
Thank you, I will have into account your advice, but only refining the local area because my model is quite big (about 120.000 nodes) and it would take much processing time.
Best regards!
Thanks so much for the answer. Unfortunately it´s not easy in this case making hand calculations because of the complexity of the model, but it has sense bogus values in corners due to a coarse mesh. Actually, when I turn on "Corner data results" I find fast stress transitions along the same...
Hello all,
I have a doubt related to postprocessing results in Femap. I've made some estructural linear analisys and I've found that exist great differences in stress values in some little areas (where stress concentrates) if you active or not the corner data results. Actually, without corner...
