I am using ANSYS software for my masters dissertation which is investigating the seismic performance of a 2 storey carbon fibre reinforced plastic concrete frame. I am currently performing a static analysis of the concrete frame with steel reinforcement and I am experiencing problems with getting a solution for the analysis. After meshing, I noticed the reinforcement is not bonded to the concrete as the reinforcement elements shows a single edge/face connectivity, and when I run the analysis, I get this error (image attached). I have tried creating a new component in SpaceClaim with all the concrete and rebars in the same component and using shared topology, but it still shows the same error each time I run the analysis. I don't know what else to do and I am really confused. I am still new to ANSYS and I would really appreciate your advice on possible ways to go around it.
Thanks.December 9, 2020 at 7:45 pmpeteroznewmanSubscribernWhat version of ANSYS are you using? I use 2020 R1 but I saw there were significant new capabilities for reinforcement introduced in 2020 R2.nSome images of your model would help those who know what to do to advise you properly.nAre your reinforcements modeled as line bodies (meshed with beam elements) or solid bodies meshed with solid elements?nIf you have solid bodies for reinforcements, have you subtracted them from the concrete body to make holes in the concrete body wherever there is reinforcement?nDecember 10, 2020 at 7:45 amChiddy22SubscriberI am using ANSYS 19.2. I created the model on Revit and I imported it to ANSYS where I changed the reinforcement lines to beam elements with their relevant cross-sections. Next I changed the beam elements to links before I meshed the model. I noticed there is no connection between the reinforcement and the concrete elements and after meshing, the reinforcement showed red lines (single connectivity). I have attached images of my model including the meshed model. nI have tried creating a new component on SpaceClaim with all the part of the model in the same component and using a shared topology, But when I do that, the meshing is poor and when I try to sweep it, it says there are hard bodies and the sweeping operation fails. When I run the analysis with all the parts of the model in the same component, the analysis stops due to Error (An unknown error occurred during solution). I also tried creating the model from scratch on Design modeller with only main reinforcement and no transverse reinforcement. I used line body for the main reinforcement, but I still get the same error as the previous models. In all the models I have created thus far, the reinforcement shows a free connectivity and there is no connection to the concrete bodies. I am currently trying another method of creating the reinforcement as a solid body so that it has connection to the concrete bodies. Please how do I subtract the solid body reinforcement from the concrete body to make holes in them?. When extruding the solid reinforcement, I am using the slice material option instead of freezing them. Is this the correct way to do it?nThanks nnnDecember 10, 2020 at 2:08 pmpeteroznewmanSubscribernTo get shared topology to work, you must slice the solid body to create an edge coincident with the line body.nhttps://forum.ansys.com/discussion/12281/contact-between-line-and-solid-bodynhttps://forum.ansys.com/discussion/13982/transient-analysis-of-a-rc-bridge-large-deformationare-activenhttps://forum.ansys.com/discussion/4389/mesh-design-issues-for-sc-static-structuralnhttps://forum.ansys.com/discussion/13378/error-solver-pivot-warnings-or-errors-have-been-encountered-during-the-solutionnDecember 11, 2020 at 10:01 amChiddy22SubscriberThe model solves after slicing the concrete bodies along the edges of the reinforcement.nThanks a lot for your help nViewing 4 reply threads
