[Salome Meca Tutorial] Meshing with Hexa Elements

[@SB-rf2ye]

I wanted to thank you for creating all of these tutorials!!! Open source grid generators are absolutely required.

[@momosh59]

Well-explained...I am just new to your channel...what I really love is the brief summary that you present at the beginning of your video.... I certainly recommend your videos to my students and colleagues.

Great video Cyprien. You show a lot of useful techniques for mesh building in Salome Meca.

[@mna205]

Cyprien Rusu I want to make beam mesh with concrete particles inside. Is it possible to include random shape particles randomly in a beam geometry using Salome Meca? You help will be appriciated. Thank you

[@amizmi69]

How can we define elements size? Per edge?

[@carloswinkler868]

Parabéns e muito obrigado, seus tutoriais são incríveis.

[@nikolaosberatlis3942]

Is it possible to stretch the mesh distribution along the edges?

[@GauravGupta-by1ml]

As it is based on GMSH. It will be there.

Thank you for the nice video. I would like to ask if it is possible to mesh the geometry of a extension coil spring, whose coils usually lean on each other because of the pretension inside (so that there would be self contact of faces )? If yes, what could be the trick of it?

Very good!

Hi Cyprien, very nice work, please keep it up. I have a question to as well if you can answer, how to set dimensions to mm scale in Geometry module i.e. In the Geometry module, how to set preferences for visualization of geometrical figures or basically how to access the geometrical preferences window ?

[@Feaforall]

There is no such setting in Salome. The way it works is that you have to choose all your units to be coherent. The easiest is to use scientific international units that way you can’t go wrong (m-s-kg). If you want to use mm, then you will have to take mm for all the other quantities. Pressures will become N/mm2 for example

Hi Cyprien, do you know how we can generate o-grid by Salome? Thanks a lot

[@Feaforall]

What do you mean by o-grid, first time I hear this term?

[@dac91Col]

Very good, the key 6:35

Hi Cyprien, thanks for all the time you take in making these amazing tutorials. I failed to repeat this tutorial using the new Shaper module (I'm using Salome 9.7.0). Have you tried the Shaper module with this tutorial? Regards Pablo

[@pablocaron]

I found the solution to my problem. I will try to list the steps for further reference: 1) Open salome and the shaper module 2) Create a new part 2) Do the square in a sketch defined on a plane, XOY for example. Then extrude this sketch 3) Repeat the process to make a circle formed with four arcs. Then extrude this sketch --> As a result of steps 2 and 3 there will be two solids in the Results section of the tree. 4) Create Fillings selecting the vertical edges on the previous solids. 5) Then you can create the Partition by selecting the two solids and four fillings. 6) Finally you can mesh the part as explained in this video. I will try to make a video tutorial to ease the reading of these steps. Regards Pablo

Hi Pablo, This tutorial was covering up meshing techniques, not how the geometry is created in shaper. I have some shaper tutorials on this channel though, have you watched those?

[@pablocaron]

Hi Cyprien, Yes, I saw the shaper tutorials. I think that I got most of my skills on using Shaper by seeing those tutorials. Again, thank you for your help! Pablo

hello cyprien, i have a small question about salome that it could help me a lot, i have created different meshis (triangulation) from different groups faces, but i can compute one at a time... 1. is there any place where i can compute one after the other one without needing to be infront of the pc when the first one finish? right now i need to compute the first, wait till finish,compute the second... etc... that is a little bit awfull as I can not leave salome computing all night. 2. is there any way to mesh in parallel with salome? i could not find any information or the things i read were saying that it was not possible.. thanks

[@Feaforall]

Hi Franco, there is no batch manager as far as I know (maybe in Astk?) ... but you can build one with python. It’s a bit difficult to do if you do not have experience with python and programming. I will think about making a video about that ... this would be a good tutorial

[@pulycenter2093]

Is it possible to use Salome just for creating the geometry, meshing it, put numbers for different faces, volumes, points... and then just export this geometry without any calculation in a GMSH?

[@Feaforall]

I think it’s possible yes

[@pulycenter2093]

@@Feaforall and do you know how to do it? cause ive tried creating fields but it doesn't work...

[@Feaforall]

If it’s not an option in Salome menu, then you can try to do it with Aster Study. Just do a LIRE_MAILLAGE and then a IMPR_RESU and choose Gmsh is the output format

[@Leinad4291]

Thank you very much for your video. Have you found an alternative way to remove the edge from a cylinder? The same edge (as 9:45) is created when circles are extruded in Shaper.
