Learn how to use ANSYS Mechanical’s component mode synthesis (Craig‑Bampton substructuring) to create reduced‑order models, cut solve times for large assemblies, and verify accuracy with simple checks.
Learn how to decide when to use bonded versus frictional contact in Ansys Mechanical for bolt preload studies, with a concrete bolt‑through‑plate example and guidance on mesh convergence and solver settings.
Craig-Bampton substructuring in Ansys Mechanical condenses large assemblies into reduced modal models. Here's the workflow, the accuracy trade-offs, and how to verify results against a full solve.
Learn how to set up Augmented Lagrange contact in Ansys Workbench to control penetration and obtain stable nonlinear solutions.
Stop guessing your mesh density. Learn when to use manual convergence studies for validation versus Adaptive Mesh Refinement (AMR) for computational efficiency in Ansys Mechanical.
Deploying Ansys workloads on a Linux HPC cluster managed by Slurm and equipped with InfiniBand occasionally results in MPI initialization errors such as "multiple pkey found" or connection failures. The objective is to run Ansys simulations reliably without these MPI‑related obstacles, while respecting the cluster’s job scheduling constraints and ensuring th
When starting MAPDL from Python using ansys.mapdl.core.launch_mapdl (as shown in the shared‑topology example), the process is launched with the user's current credentials and environment. In a Slurm‑managed cluster that also uses NFS/BeeGFS storage and MPI over InfiniBand, what specific steps should be taken to restrict the MAPDL process to the minimum requi
DNS Resolution and Gateway Communication Ansys Remote Solve utilizes a Gateway server to broker the connection between the local client and the compute cluster. While the job may successfully submit and execute on the cluster, the process often fails during the phase where results are returned to the client. The system relies on the compute nodes being able
Goal Select either the explicit or implicit ANSYS Mechanical solver for a crash test with large deformations and contact events, aiming for accurate peak force prediction while keeping run time reasonable. Constraints Large deformations, high‑frequency contact dynamics, sensitivity to mesh refinement, and the need to avoid excessively small time steps that i
