How can I find an element based on its ID?
I have the following error and I am trying to spot the problematic element and model region.
Element volume is smaller than limit (1.e-40) for element: 68413.
RMB on 'Mesh'
Under 'Options' select 'At Element number'
(Make sure under 'Advanced Option' select either 'Element' or 'Node')
Type in the Element number and LMB on the green +
Thanks for your reply.
Unfortunately this is option does not appear in my case. I have the first 4 shown in your screenshot.
I cannot locate the element using the other methods as it is probably inside the body volume.
I am using SW Premium 2016 and I am guessing this feature was added in newer versions of the software.
Did you click on the 'Advanced Option' down-arrow? If you don't select 'node' or 'element' then that option will not be highlighted above.
I did. Here's a screenshot.
That is very odd. I'm using 2017 and I recalled using the same feature on previous (2014) versions. Well, I'm stumped.
It is a static structural analysis that involves a combination of solid and shell elements.
Checked with solid only and shell only meshes and the option to address element ID does not appear.
Thank you for you time James.
That might be it (mixed solids & shells). I usually only do solids.
I don't think so.
I setup some simplified examples that have the same configuration as my main analysis (contacts, connectors, solid-shell interaction etc.) and they all ran without any issues.
My main analysis runs fine with only shell or only solid bodies but I get the element volume error when I combine them. Without locating the problematic area I can't tell what I need to do to fix it.
I made some modifications by guessing on what might be wrong but no luck.
No, I meant the "in order to find it" part, not the actual running part.
The 'Probe at Element/Node Number' functionality was introduced in SOLIDWORKS Simulation 2017. Please see KB solution S-019422 for details on an alternative approach for previous versions. Another useful functionality for such cases could be Mesh Sectioning, which was introduced in the 2016 release.
I did use your method but I cannot find the element number in any of the solid or surface bodies of my analysis.
Could it be a connector (connectors are using rigid elements though) or contact element?
Difficult to say without further troubleshooting - my recommendation is to reach out to your VAR for investigation. If you want to troubleshoot yourself, take a look at KB solution S-065116. In general, suppressing/excluding items in your study tree can help identify factors involved. If you have connectors, distributed mass, etc. in your study, check if temporarily removing those affects the behavior.
I think you can display the mesh quality and check the aspect ratio.
Then the bad elements would show up. At least, you would know which area needs more attention and
you could alter the element size accordingly.
I have tried this as well. I always perform element shape checking and nothing seems to be outside acceptable limits for this one.
I have checked all the usual suspects and also tried several meshes from coarse to very fine and mesh controls for each body.
I have a suspicion that this bad element is a contact element.
Could this be the case?
Are there any ways to investigate this?
Thank you for your reply.
