Troubleshooting Abaqus/Explicit analyses that use contact pairs

WebOct 22, 2024 · Check amplitude definitions (if used). Remedy: Reduce the loading rate or reduce mass scaling. Multiple contact constraints on a node Reason: Typically this occurs when a surface is pinched between two bodies. WebTwo load steps in the HydroQus model were generated. The first step was prepared to apply the initial displacement, and the second was for viewing the free-decay motion. No boundary conditions were assigned to the second step of the HydroQus model; thus, the six degrees of freedom motion could develop freely without any constraints. 4.2. flying mountain acadia
