Would be nice that the CCX Solver windows shows also the .sta file content for the no linear analysis, and all these info be stored inside the model file, result branch. So if is clicked again the same window could be reloaded
-
There is no way to re-open the solver info, would be nice to be stored as a text in the solution branch.
-
Thanks for this new release. The mw.new_component() is ver usefull, have modified my script to create spiders so they fall in a new component without user interaction. Now I will try to make a new scrip to convert all the groups of elements (from Sa…
-
I have made some test in the past, but if I understood well, the new version of Mecway break, ignore or change the different couplings in the attached file. Maybe should be redone using custom ccx cards directly. https://we.tl/t-flrVw7QWIb

Guess that insannely high stiffness transfromt to a rigid element, like the RBE2. The best to me is that is visible in the postprocesing :-)
-
Great! You should post in the Scripts post, is very usefull.
-
It doesn´t exists "lines" in Mecway, you must create first nodes by coordinates (there you must put the "minus one" thing), then line elements using those nodes. About your spider problem, what I will try to do is 1) Create an empty component call…
-
Looks like in your case the best is using the last node of the initial selection as reference. Imagine that you have a rectangular or circular area with al the nodes, and the reference is in the middle, so you can actually select all with some of th…
-
Hi, very interesting application. I have made a script to change the coordinates of the selected nodes to a specific one. As I don´t want to write by hand, and I know that this position is defined by a present node, what I do is first, select the re…

Have used very little, but they are not complex to understand if you open with a text editor. I will make a new approach to OpenFoam.
-
There are some very well explained tutorials in Youtube on how to prepare the models for OpenFoam in Mecway. They export the initial model as STL and then the mesh is created with OpenFoam with some available to download windows scripts.

@disla, is a great modeling trick. The circular beam element in CCX is new? Because as far as I remember all my CCX beams were expanded to hexa elements, not this octagonal prisms. I have checked, and for solid circular section, the expansion is to …

In Netgen standalone app, there is a tool called Geometry Doctor to fix that kind of geometry small errors.1

Related to @dculp comment, what about a way to save the state of the view (model orientation, scales, deformation, etc etc)? I recognize that reporting is a time consuming task that could be benefited. Another related improvement would be a way to s…

Hi, @Sebastianmaklary , what I do to surpass this uncertainty is expor the faces that will be in contact were I has to appy TIE, so ones will be upper and other lower sides of the sheet. Then you can play with the shell offset to take in count this.…
-
Another one! • Add more info in the result screen, as: Program name Solver/Analysis type File Name / Configuration Name Date / Hour
-
Hi community, my new suggestion to this useful program: • Posibility to hide/unhide individual boundary conditions • Option to open the files with all the branches of the tree colapsed (could be in the Options/Default model) • Store the solver log …
-
Based on the code of @JohnM: Info window with diameter, radius and center of a circle by 3 points (just info, no node creation) @Victor, is there a way to know which length units the user is using? I have hardcoded the results in mm, but would be …
-
I agree with @ddraht , since we lost the visual representation of the bonded contact take more time to find out every pair of contact in case that they are several. Also for the node/surface/element selector, could it be moved to the menu area, but …
-
Mecway has very good UNDO option, it remember an unnusual lot of big changes on the model. Also you could do intermediates saves with different name of the model.
-
Nice update Victor! Related to @Sebastianmaklary comment, would be nice to have the option so choose the solver (Spooles, Pardiso, Pastix...) when the user select CalculiX as solver, and in the Options windows a place to specify the number of cores…
-
That´s amaizing @disla ! I remember have seen a FEA model of a roller coaster with the buggy moving all around, does this kind of modelation in Mecway/CCX take in count inertial loads due to speed of movement?
-
Thanks @JohnM ! I'm working with the internal solver so this is not a problem, but is good to know also for CCX. That "Modify Keyword" feature is very interesting :-)
-
I found it :-) Would it be nice that the menú option would be available from the results itself, and an option to writte it to a new file.
-
thanks! @prop_design Now I realize that this exact mesh can be done directly in Mecway meshing with surface elements (with the option to use quads), and then revolving to get the hexas.
-
I would start with a mesh generated by Netgen standard inside Mecway (taking in count the size of the elements to have at least three in the main thikness), so then the mesh and BC can be associated to the imported CAD geometry. If standard Netgen d…
-
Maybe you could solve your problem, make a copy of the file and then remove all the bc if you don't want to share how you did it.

You could open your CCX results (.frd extension) with FreeCAD, and then export as STL, even in deformated state. Now I don´t remember well if is FreeCAD, Salome or Paraview, but is possible, I have even 3d printed with stress colors a deformated mod…
-
@LorenzoS, the first thing that you must understand is that not always the finished CAD model, with all the small details is the best for FEA, there are a lot of features that will complicate your mesh innecesary that will not affect the results. Al…
