NFX STR error 2115
=> error 2115 occurs when calculating elements.
It occurs during “element rotation calculation” or “element stress calculation,” and when it occurs, bisection is usually performed.When looking at the message, it seems to have ended with an error straight away without any bisection.
In this case, it seems that an error occurred in calculating the initial force as the stage was passed.
It seems that either the solution from the previous step was very wrong, or a very unusual condition was added in this step.
