Hello, everyone.
I have the following problem that I hope you will help me solve.
As can be seen from fig1 I have two partially overlapped panels bound by beam4 elements.
when I launch the static analysis and I go to plot the long voltage y (plnsol,s,y) appears that "thick" of tension in red that I have not been able to explain myself.
I initially thought it could be caused by the presence of some elements but it does not seem so (in practice along this shell181 panel beam4 and combin14 elements are distributed).
he who is following me told me that it could be a problem related to the mesh of that area (where there are hard points that, in fact, always give problems during mesh).
I was wondering if there was a way to go and see if the problem is about mesh or not.
I had thought of splitting those rectangular areas into towing areas and launching the simulation again to see if something changes.
to do this I should "stack" the mesh from geometry using the modmsh,detach command, select the elements of interest and split into triangular areas with the esplit command:
/prep7
modmsh,detach
esel,s,1215410
esel,a,,154871
esplit,all
at this point I should "reattach" the mesh to geometry and do not know how to do; I don't think you can do this.
to understand if the problem is related to mesh is more logical to clean the area and do it differently.
In fact, however, there are a tide of elements that I should recreate (some of which it is impossible to recreate as I do not have original text files used to create them).
would you have some suggestions to give me to understand if the problem could be caused by the mesh "irregular" or, perhaps, some advice to understand what may be linked to this peak of tension that I cannot explain!?
thank you all!! !
