incorrect node numbering sequence

Sebastian,

Yes, the element must be identified and checked for quality as well, for instance this error has occured for bad quality hexa elements or negative jacobian in a chexa etc

However Importantly, I see that you are running 11.0, please check if you have the latest update and install it, this will most likely fix the problem. (if you do not see any modelling issues)

see Forum » Modeling (Preprocessing) » HyperMesh » To identify the software update/patch that has been installed in your machine

HW11.0.240-HWSolvers this is the latest solver update, install it fromhttp://www.altairhyperworks.com/ClientCenterHWUpdateDownload.aspx?pro_cat=HyperWorks

Sebastian,

Can you identify the element with his id? What type of element is it? Maybe remesh it?

@merula
how do i identify the element?

@Rahul-Ponginan
how do i check the element quality? the analysis ran through fine a few weeks ago

i have added the hw version information to the topic

You can mask an element by pressing F5 -> Selecting 'by ID' -> set in the number: 1208057 ... then mask the element.

This leads to, that the element is not visible anymore. By reversing it 'press reverse', you mask everything else but the element and then you got a fine chance to see it 

For checking the element quality: Mesh -> Check -> Elements -> Quality index

@merula:
Thank you, i have found the element (it was a very weirdly shaped element that looked like a glitch in a video game) and removed it. Analysis runs through smoothly!
