How to Fix Errors in Abaqus by Modifying the Step and Increments for Beginners: Part 3

Too many attempts" and "Time increment required is less than the specified time” are two common errors in Abaqus. These are mostly caused due to making mistakes in creating steps. Abaqus provides various steps such as heat transfer, general static, explicit, and implicit dynamic steps. These define the type of the simulation, and each required different details to define. The Abaqus requires dividing each step into multiple increments to solve the model. The software gives you the option to control the size of the increment and making mistake leads to an error during the simulation process. To avoid these problems, you need to understand the concept of incrementation and step time. Here we first explain the initial, minimum, maximum, maximum number of increments, and max. allowable temperature change per increment. Then we will explain the common mistake in heat transfer and mechanical model by showing 5 examples. We go over each example and check the problem then we try to solve them by editing the step details. The tutorial video: This video explains the common error called "too many attempts" and "Time increment required is less than the specified time" in Abaqus for beginners. If you feel you need to know more about the process of solving and modeling in Abaqus. please watch the following video: https://hyperlyceum.com/product/incre...

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: 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.
