warning message

[Anonymous]

Dear Sir,

During running of the model, I got the warning message  (The martix is not positive definite-the critical load may have been exceeded-see attached file)  .Kindly clarrify.

Note that I have uplift water pressure loading case (non linear analysis).

This warning indicates that the applied load may be excessive and cause the structure to be no longer stable. Try to run buckling analysis to check the value of the critical coefficient.
