In this section, you find some information about ABAQUS. Here many frequently asked questions have been answered. As usual, if your have any question you can leave it in comments.
Incompatible mode is a feature designed to improve the bending behavior of low order elements. Briefly, by using this feature elements shows a more realistic response under bending moments. As I have focused several times in my video coarse, deep understanding of different features of a software is the most part of any numerical modeling. […]
If you are new in ABAQUS, confronting different errors might be the most disappointing aspect of working with numerical software. But if you are patient enough, and continue working and thinking deeply, after a while these errors give you an amazing insight into numerical methods. In this seri of articles I will show you some […]
Many beginners come with the question of what are ABAQUS measurement units. Unlike most of numerical software, ABAQUS does not have any build-in unite system.so please Do NOT include unit names or labels when entering data in ABAQUS. All input data must be entered in consistent units. This table shows the compatible units. Before starting […]
Shear locking error As it is said earlier, reduced integration elements are suffering hourglass effect due to their low bending stiffness. On the other hand higher bending stiffness of full integration elements might cause another numerical issue, called shear locking effect. Fully integrated first order elements, such as solid elements, Timoshenko beam elements, may exhibit […]
In finite element (FE) methods, the calculating of element stiffness is of a fundamental importance to compute the deformation of the element. Depending on the complicity and importance of the problem the stiffness matrix can be calculated by different accuracy. One of the well-known method for numerical integration of two-dimensional integration is Simpson’s rule, which […]
