Abaqus is a friendly user software to solve the finite element method models. The software covers a large variety of models by providing many options to users. To simplify the modelling process, it uses many predefined parameters to help the engineers to save time on the modelling process. However, depending on the model each might require different parameters and skipping them leads to creating errors in simulation. As a result, in Abaqus, you might face many errors which some are easy to solve, and some are difficult. The most comment errors are the “Too many attempts” and “Time increment required is less than the specified time”.

Where you can find the type of error:

You can find the errors from the message file or STL file in the Abaqus job directory. The easiest way to find the error is from the monitor section in the job manager. From the incrementation, for the "Too many attempts" error you could see that the last 5 of them were reduced. For the “Time increment required is less than the specified time” error you could see the last increment size is smaller than the defined increment in your step. There is also a comment in the report that also explains the error to you.

These two errors might appear for many reasons which make them very common to appear. These errors explain the solver tried to solve the simulation but due to some mistake in the model, it aborted the process. The errors might happen cause of mistakes in, any module such as material properties, step, load, and mesh. While every module is important, the load and boundary condition definition in simulation have the most important impact on results. In this video, we try to explain the most common mistake that might happen in the load module that creates the errors explained before. This video is short and helps you to find the error in your simulation quickly.
