PERIODIC MESHING BUG?

Post by UOMO »

Dear Louis,

I'm trying to export the model in the link: (https://dl.dropboxusercontent.com/u/63692257/model.tg3) as volume mesh. Resulting mesh has opposite nodes coinciding in x-direction (periodic mesh), but it is not the case for the y-direction. Any suggestion to this issue?


Thanks in advance,

Best,

/UOMO.

Hi UOMO,

Sorry for the delay replying - I've been away at a conference. You're right, there seems to be an issue with the periodicity in one direction. I'll take a look at what's going on but I'm away at a software engineering conference for the rest of the week so it may be into next week before I get back to you.

Best regards,
Louise

Have you by coincidence have figure it out what happened with the periodic mesh?
Thanks!!.

Hi Uomo,

I'm trying to work out what is going on with the meshing. Is there a particular reason why you have a domain which is two repeats in the y direction? If you reduce the domain to one repeat in the y direction (ie the domain is square, one repeat in both directions) then the periodicity of the elements is fine.

Best regards,
Louise

Hi Uomo,

I think that when I got the correct repeating elements in both directions that I also deleted the last two nodes on the x-yarns as well (this then makes sense with the repeats which are set to 0.4).
