Hello everyone,

 

i am a new user and got a training in Hypermesh and now a few workdays with Hypermesh. while i find much help online, i have some trouble with the 'Check Elems' tool

 

While generating a mesh, i went to the length check (2D --> Automesh --> checks) and it displayed that no elements violate my mesh quality (Picture 1)

Then i went to the 'Element check' under tools and it displayed a violation with the same criteria (<2mm, Picture 2).

Then i measured myself and the range was over the 2mm (Picture 3)

Can anyone explain this to me? i am a bit confused right now,

 

thanks in advance for the help

    Hi,

     

    In 2nd image I see:

    'length < 2.00

     length > 2.00' 

    In this case elements with length other than 2 will violate the criteria. You can change the 'length >' value and check.

     

    Thank you

    Thank you for the reply,

     

    i only clicked on the 'length <' button, so it showed Elements smaller than 2. I uploaded an updated Picture with an other entry for the 'length >' Button so it doesn't confuse here.

    On the panel, click 'setting' and apply element length measure method as 'shortest edge'.

    Thank you! 

     

    thats what i was looking for. Now i know how Hypermesh was calculating it, and it makes sense.
