Errors of using Press-stressed Modal Analysis

Hi all,
I've met problems of using pre-stress modal analysis. The Static Structural simulation turns into "red flash" not "green marker". Although the simulation still run, I don't know if the results are trustable. It's an inflatable body, using rubber material, with 1/16 inch thickness and 10 Pa pressure inside. The boundary conditions are the 7 vertexes of this body. The whole body is around 2 meters long and I'm using 0.03m mesh size. The error says: An unknown error occurred during solution. Check the Solver Output on the Solution Information object for possible causes. The warning says: The solution failed to solve completely at all time points. Restart points are available to continue the analysis. Large deformation effects are active which may have invalidated some of your applied supports such as displacement, cylindrical, frictionless, or compression only. Refer to Troubleshooting in the Help System for more details.Although the solution failed to solve completely at all time points, partial results at some points have been able to be solved. Refer to Troubleshooting in the Help System for more details.The unconverged solution (identified as Substep 999999) is output for analysis debug purposes. Results at this time should not be used for any other purpose. |
