For rubber with contact we use first order hexa elements, there you could reduce a lot the node count. We predict very accurate the load/deflection curves of the rubber parts.
When I was in the automotive industrie modeling rubber parts, we pay special attention to meshing (and bc) to keep the nodel count low and be able to run our no lineal problems in a razonable time. We use manual mapped mesh, hexa meshing, and contro…
The new spring element visual representation is awesome! I though that would be visible only in preprocessing, but is also visible and deformable in postprocessing, really really beautifull and usefull to better understanding.
Coud be added somethi…
It works! Now I can import a big UNV assembly mesh into an empty Mecway file, and get all groups of elements converted to components. I have tunned the script to create and assign a basic steel material and assign to each component, and then delete …
Hi @Victor, I have modified this last script to create a new material and assing to every component, and it works very well, the problem is that when I try to assing a Young Modulus of 205000000000 Pa (205000 Mpa) to the material (using mw.set_mater…
Hi, @Lhartey , attached a link to a video of a steel tower solved with Code_Aster, the interesting is that the model (step, only lines) is available to download, so you could try to reproduce the results. Mecway will not import the stp, but you can …
As far as I remember Abaqus CAE doesn´t need so many tokens to run, is the solver what needs a lot. Maybe could be interesting see if is possible to buy only Abaqus CAE and do the meshes there.
With Siemens NX or Abaqus CAE you can work at geometry levels such as "delete that wire", "move that wire end to that end line and avoid having stupid 0.2mm lengh dirty edges" and things like that, but they are very expensive. Maybe with moi3d you c…
@JohnM , Solidedge and Solidworks have tools to delete faces (radius, chamfers, holes...) that can work with imported geometries. I agree that after making lot of simulations you learn to draw your models in a clean way, first the big shape of the p…
Well well well, @cwharpe, could it be that I herd that you are open to script suggestion??? :-) I have some in mind that could be very usefull, but no code skills at my side. What about:
1) A script to convert all the element named selections (grou…
The true is that the 3D cad model for this cases is normally use as a base to redraw the frame with lines for the FEA modeling. Draw a couple of lines and find a way to export it before making the whole model again.
If it were made with perfect…
@traemand I model structures like that, CAD and FEA. I use Solidedge, where those structures can be modeled using a special feature that draws profiles over an 2D or 3D sketch. These sketchs can be exported as stp, if they are 3D sketchs, and the op…
FreeCAD lacks of a standard (unified) assembly and drawing enviroment. There are several assembly/draft workbenchs, but all work in a more complex/weird way than traditonal comercial CADs. That´s why I like Alibre, it just works (well :-) )
In the versions were the TIE was highlighted with small black balls, was easier to see if the element surfaces were hiden, and the mesh color was adjusted to cyan (same color as undeformed mesh by default). With this configuration I found easier to …
I'm using Alibre Atom at home for creating models, have bought a licence a year ago (about u$d 149). Some operations must be done in FreeCAD (split surfaces and boolean), but still is the best option for starters, freelancers or hobbyist in my humil…
Hi Victor, is there a way to add an option to the importing of UNVs meshes from Salome to convert the groups of elements in components? Related to this, a new option in the contextual menu of the Groups branch of the model tree to convert all groups…
You could drag the nodes of some failed elements to make it acceptables directly in Mecway (or even delete the elements), but is easier to remesh in Salome with different parameters.
@traemand, it´s not possible to do multiple selection in the model tree. What you could do is adjust the default options of mesh in the Tools/Option/Defaults windows to a more suitable values for most of your parts, and then only edit those that wer…

@Lorenzo, in Mecway, first select the group in the model tree, the elements become selected in the model view. Now press the secondary button of the mouse over the selected elements in the model view, to bring up the contextual menu with the option …
