Hi 

We need help with creating a hex mesh for an assembly. We did not find any good tutorials on altair website. Can someone please help us with this?

Thanks,

    Hello 

    Have you looked on our Youtube site?

    https://www.youtube.com/@AltairHowTo/search?query=hex

    Or our eLearning ?

    https://learn.altair.com/totara/dashboard/ 

    There is a module on Solid meshing.

    Hi Jason,

    Thank you for the information. I went through the material you sent. It is really good. Thanks so much. I was able to mesh quite a few solids using the examples.

    Although I am having difficulties meshing this solid bar. I split the solid into mappable solids but not able to mesh them. Can you please have a look at it and suggest. 

    I am attaching the step file of the bars.

    That is a tricky area due to the intersecting/conflicting holes. One idea I had is to partition the side hole like this and delete or do not mesh the curved areas. Then you can just mesh the blocky hex elements and morph after

    Hi Jason,

    I dont know if I completely understand you. But will that not result in a square cut out rather than a circular hole??

     

    Thanks,

    That is why I mentioned you can morph after. 

    But the hex mesh itself should be much easier
