Update, I open and recalculate both configurations, and then it display different results... great I thought. I delete again the results and rerun and again is showing the same result on both config.
Have deleted all again, and compute the first c…
This is my first try with configurations, I can't find a way to have two different results, and if I delete one result then the first gets corrupted (or at least the display).
Wolud be great to be able to see the different configurations side by s…
Have tested
• Gmsh, only adjusting the element size and using local refinements (need to investigate what custom modifiers should I apply still). I felt that is slower than Netgen, but sometimes can produce better meshes, so is a good new feature…
Have the same concerns on Mecway, the clasic solutions is use Salome or Roshaz if you want 100% quads. Have tried lot of configurations while exporting from the CAD but none works.

After thinking a little guess that will be better to model the pin as a solid and use contact, otherwise RB will artificially restringe the posibility of deformation on the holes.
You could define a different RB for each part (guess that you will need four reference nodes in the same point... a little tricky to manage in Mecway), But now you need to link both reference points (those that control displacement, not rotation) in…
Could it be that as the model is IGS you have only a shell mesh? Maybe if you import as STEP Mecway will produce a solidmesh. Or use the Mesh Tools\Automesh 3D on your existent shell mesh. Guess that you must check node conectivity first in the seco…
Thanks Andrea for the comments!
That's are the things that make's me escape from shell elements while I can, not only in CCX/Mecway but any other solver. For 3D solid modeling guys as me there are severals things to take in mind to don't make mista…
Very often the load directions are aligned with some edge or face of the geometry, so using it directly is easier than compute the vectors. No, I will not put a new node to align a force, is always using existing points, edges or faces.
Great! Have tested and works very well, for doing it by means of CCX cards I have to write and think and check the references manual as is not everyday used, but now is so easy. The only thing now is the name, I meant is not doing a support but appl…
And what about using TRANSFORM card to apply radial deformations on cilindrical node sets? I found usefull that card in that situation, don´t know how to apply such a condition without TRANSFORM to circular coordinate system the node set
Regards!
Hi, don't know what exactly means the local h too small, but what can I tell you is that the bending radius and thikness are too small compared with the overall dimention of the part, so for having a good meshing you would need a very small element …
Hi Andrea, very interesting information. True is that I don't use almost shell elements, and even less in CCX or Mecway. Why is happening this, is due to the solver or any solver will have the same behaviour?
Thanks in advance
I have removed one rigid body at one hole, so now the horizontal bar is free to rotate, and change the load for a displacement (20mm in vertical direction), to see if increasing the rotation this growing in the holes remains or increase also. If we …
I will try to reproduce using DCOUP3D and see what happens in the holes. This growing is small, we are seeing the model scaled almost x2300, but should be zero.
This is the model solved using only RIGID BODY, but as we can see in the holes there are "radial" growing, this is something that I have seen in the past using this method and never find a way to solve or at least understand. If the nodes of the hol…
Just a question, using a RIGID BODY between a center node and the surfaces of the holes would create the same condition? I use very often RIGID BODY, but never DCOUP3D.
By the way, would be nice to have both (RIGID BODY and DCOUP3D) available on Me…
In my humild opinion, the more logical from the point of view of the FEA would be in the material, because one would like that all of element of the same material behave the same. If it would be in model, then all materials/components would have thi…
Great news Victor! Can you look for some way to move the option of reduced integration elements from a "program option" to a "file option"? Now can be a little problematic if we forgive to swich of the option on models that don't needed it.
Regards
Thanks Andrea, have tested and works. As I say before, the implementation of the tool in Salome is a little confussing, we are using something that says "create a set of ELEMENTS" to create a set of FACES. What is the logic behind that???? I'm sure …
Well, we can speak a lot on the matter. Guess that university try to teach the best they can... And we must recognize that Abaqus, is one of the best tools on the market. On the other side, students will like to invest his time and effort in learn t…
In fact with the new selection tools available in Mecway, is easier to create the groups there than in Salome, even having loosed the CAD geometry association.
