Hello dear colleagues
Hope you're fine.
I'm trying to model a threaded connection with a 2D axisymmetric model.
I need to make several models with slight changes and differences.
In some models, once the job is submitted, before the analysis gets started, it gets aborted due to "some nodes have Negative coordinate values" error.
When I check the error node set, they are all placed on the axis of symmetry.
I tried several ideas to work this out but none of them was successful like:
>changing element type,
>constraining the part in the direction prependicular to the axis of symmetry
>Using another datumn coordinate system
I appreciate it if you have any ideas to fix this error.
PS: some other models get solved without this error while these models are copied from one another and I couldn't see any difference seem to be related to this error between them
It looks like you're encountering a challenging problem while working with a 2D axisymmetric model of a threaded connection. The error you mentioned, where some nodes have negative coordinate values on the axis of symmetry, can be a subtle issue. Here are some strategies that might help you fix the error:
Remember that seemingly small differences or errors can cascade into significant problems in complex simulation models. It might require a systematic process of troubleshooting and comparison between the models to pinpoint the exact cause of the issue. If you continue to experience difficulties, working closely with a more experienced colleague, or even directly with software support, may help you resolve this challenging problem.
Joshua Depiver Hello , can you please help me with this concern ?
i use USDFLD to compute phase fractions (3 phases) , law kinetics are written in SDVs , everything seems working good except the fact that i have negative values in the middle of my axsymmetric model , negative values are displayed also in the legend of SDVs which is not reasonable at all ?
