VDload subroutine code is one of the most simple subroutine code you can start learning. It is a subroutine in the Abaqus explicit which has many applications. One of the advantages of using Explicit Solver is its strong capability in contact analysis. In some cases, such as the movement of train wheels on a rail, which requires modelling various components or simulating the movement of a vehicle on a bridge it is beneficial to use the explicit solver. To define the complex load distribution or movement on components for explicit models the VDload subroutine is helpful. You can define complex mechanical loads for your model with minimum effort. The usage of VDload is similar to Dload and most of the variables are the same. An example of the VDload subroutine in Abaqus is provided in this video. In this tutorial at first, we introduce the VDload subroutine and give you some tips about it. Then, we will explain the subroutine using an example of the moving load subroutine. The plate is fixed and because of the load, you can the stress distribution during the time. In addition, in the PowerPoint file, you can find good information about the subroutine code.
