Dear All,
I'm running a nonlinear analysis of a masonry structur of about half a milion of elements. Elements are of Pyramids type TE12L and some other elements (only about 5% of the elements) are shell elements of type T15SH. I'm using Druker-Prager model in compression with smeared cracking model (multi-directional fixed crack model) in tension. The mesh isn't so fine and I'm also seeing an warning regarding it stating.
SEVERITY : WARNING
ERROR CODE: /DIANA/LB/EL30/0094
ERRORMSG.W: One of the angles between edges at node 46028 of element 100 is
less than 10 degrees or larger than 170 degrees.
My problem now is that during nonlinear analysis I'm always seeing a warning stating the following:
SEVERITY : WARNING
ERROR CODE: /DIANA/NL/LB41/0212
ERRORMSG.W: Unloading: Crack nr. 1 - EC-new 0.78100E-03 - EC-max 0.78030E-03
Check crack-status.
Is this warning related to the method of solution, I'm using Secant method (crisfield method) ??
I don't how to check crack-status as Diana is recommending me and also I don't now how to fix this warning and also is the warning of minimum angle found in some elements are related the warning of crack-status ?.
Thank you very much.
