Error in rigid body simulation2 Attachment(s)
Hi, In a ridid body simulation I get the next problem.
* Point 90 : 264.494074 226.399433 -93.291688 Normal -0.000000 0.998185 0.060215 Violation -8.958018e-011 NormalVel -3.993559e-012 -7.923145e-012 1 2 734 997 00 * Point 91 : 264.494074 226.639598 -93.883704 Normal -0.000000 0.758020 0.652231 Violation -1.841433e-010 NormalVel -2.027420e-012 -4.012020e-012 1 2 734 997 00 Murty algorithm failed, trying PSOR Small pivot found during PSOR LCP solve PSOR algorithm failed, Abort No set of active contact stops can satisfy all the constraint equations. Solve cannot proceed Solve failed Error found at time 2.800000e-001 Solution terminated before normal completion Total number of time steps: 7 Average time step: 0.04 Number of rejected time steps: 0 Number of discontinuities: 0 Number of saved transient configurations: 8 Maximum relative error: 1.48466e-011 (%) End of Transient Simulation. CPU Time 31.1406 Elapsed Time 129.214 Analysis of model redundancies: Joint Revolute - DPMPLink-1 To FD-1 shows some constraint redundancies Z Translation constraint equation was at time redundant X Rotation constraint equation was at time redundant Y Rotation constraint equation was at time redundant The simulation is from 0 to 5 seconds. It only solves 8 steps aprox. DPMPLink-1 To FD-1 joint detail is attached and solution configuration. Thanks. |
