Have tested the new node-surface coupling features on the internal solver and they are great, is a big advantage for working with with real shell elements. Have you thinked in adding no lineal materials to the internal solver as well?
-
Well... just don´t do too much zoom :-) In my experience works razonably well for being a free software (probably the best of the open source world if we put in the scale the easy setup and having so good preprocesors available as Mecway and Prepom…

Thanks for this update, the new simmetry bc for beams works really good, attached first test with a security cage
-
Just a newbie question, why the MFRONT library of materials (and others) is not directly integrated in the standard CCX distribution? There are a lot of post here and in the CCX forum on how to install/compile this feature
-
@Victor, probably the easier way to get a midsurface would be adding to the move/copy tool an extra option to use the normal+ or normal- as direction at a specific distance, the same as the extrusion tool have it today. After that the user should d…

I found today this nice paper about reinforced concrete, maybe could be redone in Mecway/Calculix https://www.linkedin.com/posts/aymanelfouly_els-software-progressive-collapse-validation-activity-7148028782396719104-3Dno?utm_source=share&utm_m…

@kuhtip there is no way by the moment to identify the user unit system, so you must work in meters and Newton in your script as is the internal unit system that use Mecway. Would be great to have a custom tool bar (floating?) to add this kind of sc…

@cwharpe about putting different spiders from different fasteners in different components, have sense? I meant, is a resource to connect to the beam that simulate the bolt shaft, only those beams must be in different component in case of different b…
-
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?
