hello researchers
How I can solve this problem in my model analysis, the error message in the message file is as follows:

Could you elaborate on your model? Like what are you trying to model and how have you setup your model etc.
there is a 3 dimensional truss bridge that a shell is defined in the modelling to transform the load to main frame as shown in the attached picture
the train loading is running through bridge on the shell part
the time of the dynamic step is defined 4.54 second but it run until 3.78 second
yes, the result is available until 3.78s however the job aborted
I checked the B.Cs , it's OK
It is interesting that If I submit the model for speed of train 160 or 180 km/h this error abort the job
but for higher speed of the train the job run fully correctly
Hello Elham Askari,
I am facing the same problem, have you find the solution for this error.
Hello Gajendra Pandey,
I am trying to mimic the compression test i have performed in UTM. I have creating contact between rigid plate and irregular shape and apply interaction property(frictionless). The plate is moving till it comes in contact with the surface of irregular shape but after that job aborts and the deformation is not achieved. The force and the contact interaction is not achieved in the 5th increment of static step.
I am attaching my inp file please see to it, your effort to resolve my concern are deeply appreciated.
