automatic mesh operation or completely manual

[trabs]

Good evening to all,
I'm a student and I'm just starting to use simulation programs (for internships).

I should meshare a very particular plunger, internally has many holes and various ducts and if it opens with hypermesh becomes a casino of green lines, they are almost indistinguishable for how many there are (the piston is really very complex).
so doing a nice manual cleanup is really complicated.

I wanted to know if in the world of work, where these very complex geometries are frequent, usually you face the problem with an automatic cleanup and then you continue with the automatic creation of the mesh 3d or you arm yourself with so much patience and good will and you try to do a manual cleanup, you do the manual mesh 3d on a part of the solid and you mirror it (of course if the solid is symmetric).

thank you in advance gentlemen!

depends on what you want to get from the analysis. the best thing is to work in the cad directly and eliminate all the features you do not need. then the rest is done in the preprocessor, normally by hand, if you can get what you need with the automatic cleanup well.
However if the lines are green is already fine, at least it recognizes the edges united....
Good job

Okay thank you very much, always exhausting!
