Hello Developer team, Recently we came across an error: Error :301150 with Autodesk support and we realized (Based on Autodesk support team) that  The investigation has exposed an issue in the code: The incident is triggered for large 3D models running large deflection with mesh aggregation disabled and upgrade tetras set to either automatic or all. While the model size and type of geometry (ratio of thicker vs thin layer areas) is the driving factor, we cannot estimate beforehand if the incident will occur or not. Until a solution is released, the recommended solution for this type of models is run large deflection with mesh aggregation enabled. The provided ****ysis had gaps in the node numbering. It is important to make sure the node labels had been squeezed before running any ****ysis --> this we already tried. With this scenario there was a thought (Knowing it's very much tricky but may doable), Can we have a hybrid mesh (DD+3D) where we can have 3D in complex area where Midesh is not suitable so we have to go with 3D and other area we can keep DD (Thin area / uniform thickness area) to keep element count in control? I guess other product simulation software has such facility, may be tricky for process but want to check. Case number to know more: CaseNo:22274199. Looking forward to having feedback.  Show More
