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 …
-
Can you please explain how to create groups of faces in Salome? Thanks in advance.
-
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.
-
One of the nice features on Salome is create diferent/independient meshes for divided volumens (that share a face), but with coincident nodes at the shared faces, this is usefull for simulate bonded unions (sometimes the TIE fails in some nodes lead…
-
Yes, Salome can do very interesting meshes. I'm very interested on structurated meshes, but is very difficult to get information on how create it. Anyway don't forguet that he is using mainly Netgen, so is a matter of investigate how is exposing his…
-
Now guess that understand your problem, you meant Mecway´s components...no, they are not created automaticly, must be recreated using the groups of elements and the contextual menu, regards
-
I'm using UNICAL as well, but downloaded from some other forgotted place. I'm attaching it if you want to try. I have associated the .unv extension to the unical.cmd (cmd, not exe) file to automaticly convert the files by double clic on the Windows …
-
Create the groups of elements in Salome for each material, then export as .unv and convert to .inp using some command line utility available overthere, I made it everyday and works like a charm, Regards
-
Very good report, mesh is very important for analysis, not only the size but also the shape of the elements, I have seen very weird results (false stress concentrations) due to poor shaped elements. In my humild opinion the solvers (CalculiX, Mecway…
-
Guess that not possible to get the output from netgen in Mecway. But you can try to mesh directly with netgen standalone application using the geometry doctor to heal it, or use gmsh or Salome.
-
The actual system is good enough, with the first unit selection almost all are then uniform, but still there are some places were this is not happening. There is also some unit (guess that is Nmm or something like that that doesn't give the option t…

"In Mecway, with a 1mm mesh and after mergin nodes at 0.2 distance you get all the elements stitched." No need to make any manual editing, just merging.
-
Will try it! In case of having nodes selections available will easily the plottings tasks. Regards
-
I have tried in the past but guess that there is no automatic way. In such situations I preffer to select nodes (by means of a box selection and playing with the orientation of the model) and after swhitch to edges on the nodes/edges/element selecto…

Have tried with Netgen but it makes a non continuos meshes, even I have used the geometry doctor to heal it. In Salome, just meshing the part using simple parameters looks like if all where conected, but after checking in Mecway with Open Cracks, we…
-
Have you tried with Salome? It has some ways to join the parts and make a continuos meshes. I have made with solids and works, maybe with meshes would work also. If you share the files I could give a try.
-
Could it be that you have removed the step file from the analysis folder? Otherwise upload the step file and we could try to reproduce the error. Regards
-
Dave, I didn´t have any issues with SciTE, the only thing is that for colapsing such a big subsections will freeze the program on my pc. On the other side, Mecway refuses to open directly, that's why I was concerned on how you would be doing it. R…
-
Great! I will give a look then, sometimes I compute this case of loading and could help to avoid contact. Anyway CCX has improved a lot contact treatment in this last versions.
-
Can you explain how you apply this distribution?
-
Great, I use Roshaz also for quad meshes, that after I import in Mecway to create hexas. Do you know if is possible still to buy a full licence of Roshaz? I have looked for a simple quad meshes unsuccessfuly the last months.
-
How are you working with this huge model? What are you using to preprocess? Regards
