@dculp in Salome, there are several mesh quality parameters that you can check, and edge lenght was one of them.
-
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…
-
@JohnM , have you tried removing faces in Solidworks? I use Solidedge at work, and is possible to just delete those radius and chamfers.
-
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…
-
@dculp , the stp was uploaded by user @Lorenzo in this same thread.

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 …
-
Forget about videos :-) I was thinking in reformat and make a series of articles on my site/blog.
-
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 …

@Lorenzo, attached a tutorial for creating conformal meshes in Salome and exporting to Mecway https://we.tl/t-v0FNRrOzLt
-
Moving in the model tree, using the scrool bar for locating components or bc will make you very annoyed. For that kind of models the possibility of grouping components (the same as today for boundary conditions) would help a lot. And for assigning m…
-
And use simmetry, at least for building the meshes.
-
The model look interesting, but workng with such cuantity of components will be a nighmare in Mecway. Remove all non structural components, and surely you will have to make the meshes very carefully (by hand each one) to have something usfull. The a…

Hi, during the day will try to prepare a tutorial for meshing the assembly with coincident nodes in Salome and export to Mecway.
-
I have checked, and for getting a coincident mesh with separated/selectionable parts, must be done outside Mecway with Gmsh or Salome. You could do inside Mecway, but all the elements will be assigned to one component without easy way to separate or…
-
2) You have such "explode geometry into subgeometries" in Salome. You can even prepare shell models there, leaving one side of sheet metal parts, and then export as step to mesh and work in Mecway. 3) Now I don't remember, but look for the specific …
-
The edge selection would be very usefull. What you can do in these cases is select the nodes by hand (with a rectangular or circular selection) and then change the selection mode to surfaces to catch all at once.
-
Hi @traemand, welcome to the forum. About exporting assemblies to Mecway, what I do normaly 1) If they are few parts, in the CAD I hide all and leave only one part of the assembly, and then export as stp with the option to only export visible parts…
-
My firs advice would be simplify carefully your CAD models and then also try to simplify also the BC at the begining.
