"Use Corner data" option in FEMAP 3

[sir0co]

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 data results I can get some reasonably good results and with corner data results I get little peaks of high stress (maybe 100 MPa higher), specially in some vertex(even in areas with a fine mesh).
Do you recommend me having into account all data for postprocessing results? Or maybe this high stress peaks in little areas don't exist in the real model with this values?
I have to say that without corner data results I get a more 'homogenous' stress concentration in these areas a with a lower value...
Thanks so much in advance.

Jose

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 convergences is the only way for checking the accuracy of a fem model.

Best regards.
