      Please provide some more details about the issue. Here are some best practices for using the forum:nBe efficient ? To get answers fast, always search for your question before creating a new post.nBe clear ? Provide supporting screenshots, error messages, and background information in your post instead of attaching a simulation file.nBe precise ? Post your questions in the right categories and use correct tags to help our engineers find your question.nBe patient ? Please allow up to three days for someone to get back to you. If you have an urgent question, email your Ansys Account Manager.nBe helpful ?

      What can be the solution to the error a general failure has occurred during solution in ansys explicit dynamics

      When the solve is initiated, the checks done before the first cycle can find problems and produce warning or error messages. These are usually related to the material models, the boundary conditions setup, or the restart options. When a General failure error is seen, this usually means there are possible problems with the licensing or the remote solve manager, but it can also signify other problems. Errors or warnings can also be seen during or after the solve. The two primary reasons for a terminated solve are the Energy error exceeded and Time step too small errors. Both of them can mean a variety of problems - meshing, high deformation, incorrectly applied forces, etc. Usually observing the results up to that point or using the erosion or error options to bypass the termination should give an indication of what the problem might be.nnMore info at:nn-AniketnHow to access Ansys help linksnGuidelines for Posting on Ansys Learning Forumn
