Analysis results are saying that <em>&#8221;One or more MPC contact regions or remote boundary conditions may have conflicts with other applied boundary conditions or other contact or symmetry regions. This may reduce solution accuracy. Tip: You may graphically display FE Connections from the Solution Information Object for non-cyclic analysis. Refer to Troubleshooting in the Help System for more details.&#8221;<\/em><\/p>\n<p><\/p>\n<p>I assume it is because my symmetry region shares a few mutual nodes with MPC based remote displacements. How do i check accuracy of the analysis?<\/p>\n<p><\/p>\n<p>3. I applied anti-symmetry plane to the same surface and results showed gap between the supports along the anti-symmetry region.
