Hi @cwharpe ! Thanks for taking time to fix my poor man script. I think that the logical is that all the beam elements share the same material and component.
-
I have made something similar, I use two scripts, one for create a node in a circle based on three selected nodes. The second one takes the selected nodes and creates the spider and material. The user must select the center node as the last one in o…

@Victor , I have seen that you mention that there are some internal check of element shapes and topology, could it be implemented in future version some kind of reporting on this elements checks? At the moment the only way to have an element quality…

Hi, the new slider control for the edge threshold is very nice, now we can pick complex face selections very easily. Can you implement the same kind of control for the cutting view? I feel that the actual slider is not so accurate.
-
I would mesh carefully every element separately, maybe using Salome to get more control on mesh creation and node/element count, trying to use hexa elements where is easy to set up. Could take one, two, three days, but will finish with a model that…

It works very well, have tested with a simple aluminium rim. Thanks for this update
-
I just note that you need the hexagonal nuts. I would model separately as solids and join with TIE boundary conditions to the tube. For more accuracy, in the CAD the surface around the nuts could be splitted in order to be selectable in Mecway for d…
-
I just recreate the basic tubes as surfaces in Solidedge (I would not consider the small hexa features, too small compared against the tube, at least for an initial analysis), using a simple sweep with parametric sketchs (circle and elipse for the p…

Can you show or share the geometry? It's a lot of elements!
-
I have removed the tangential stiffnes of the contact definition, and works razonably well, I would check if there are some penetration or not
-
The "Save view" is a relly nice addition, thanks for this update @Victor!
-
Changing the solver to CCX and no lineal analysis, displacement are very similar:
-
Switch to 2nd order elements for the 3D elements and the variation will be less. Maybe with more elements you will be closer. Also the deformation is a little bit high, maybe you should do a geometric no lineal analysis.
-
Without seeing the model, I would use guides (modelded and include contact) and move away before main loading.
-
Would be interesting to see the problem, can you share it?
-
Are you tring to remove an impossed displacement? Can you apply a reverse displacement in place?
-
I was a big fan of multistep analysis (as I came from Abaqus), but after a lot of experiments (writing manually cards for the second, third.. steps) I have found that I can make all of my multistep simulations in one step using an appropiate Time Pe…
-
As far as I remember you need to use de *NODE PRINT card and request output values for RF (reactions forces and moments probably) on the reference node, that you must put in a node set before to call it on the *NODE PRINT card. This will generate an…
-
That's great, I have to make time to test it.

There are some hacks to use Mecway as preprocessor for OpenFoam, but the postprocessing must be done in Paraview. Check out this Youtube channel with several tutorials and material. https://www.youtube.com/@simcommons8090/videos I also will find u…

Hi, you must go to Menu/Solution/Find Max Min. If you don´t have nodes selected will be the global max/min, in case you made a selection of nodes, then will be related to those nodes. Regards
-
This will be a new tool, or a modification of the actual stress linearization feature?
-
I found out that if I set the minimun size of the mesh to the minumun local refinement, then it acts as in Salome
-
Hi Victor could you add in the list for future improvements the meshing refinement with Netgen? Very often we cannot force some refinement on surfaces with Mecway/Netgen, that can be done on Salome/Netgen easily. Check out this example, in the small…
-
Hi Victor, I just tried the beta of the version 20, and the Geometry view now looks really nice, the new colors for parts and edges, and the hided parts representation is also very good! Some ideas: In the Analysis settings, can be added a user t…
-
@kuhl , normally I keep the initial 2d mesh as a backup, so then I can extrude to any thickness. All the BC must be re-applied
-
@kuhl , for sheet metal part, our procedure was model in CAD as a surface model, and we model the side of the part that is in contact with another one. So then we mesh it with 2d elements, and we can choose after in the extrusion (we also use hexas,…
-
I have used sucesfully Prepomax for the determination of Mooney Rivling coefficients from a rubber part, based on compression test of the part, not from standard samples.
-
I don´t have much experience with Mecway´s internal converter, I use Calmed8 instead, that convert to only one .rmed result file that can be opened with Paraview. I have converted several no lineal results with about 50 increments (up to 20 GB) to o…

You could reduce the number of saved intermediate increments if is a no lineal simulation (maybe leaving only the last one), and also reduce the number of field variables to the one that you really need to postprocess. A last resource would be trans…
