Hi Victor
I would like if the LeftShift key could be used to select a group of Named selections.
Actually, you need to select them one by one.
I'm not sure if this depends on MECWAY but, ¿ is it possible to have the preview option in the file expl…
Hi Victor,
¿Could you add the possibility to generate a Surface into the Mesh tool > Create > Surface from a given Contour (Sorted list of nodes)?
I mean, being able to enter a sorted set of points that once closed would generate the inner …
Hi Victor,
You are right , nodal force was not the same . More nodes, more force. My mistake .Sorry.
Example of plates under shear.
Shell left side.
Laminate with 6 layers of identical properties in the middle.
Solid on the right side
Through thic…
Hi,
I have made some simple test and readings to understand Victor's sentence
"You may still get an improvement due to more integration points though".
Using many layers of the same material do not provide more accuracy. In fact, it seems to be …
I now realize that laminates could be an easy way to gain accuracy in a computation modeled with shell elements.
I mean, ccx expands shells into solids. Defining the shell as a laminate with all its sheets with the same properties we could provide t…
Hello Mishal,
I have no idea if this would be later useful to you and how accurate would be the results but ¿have you consider to model with the set Plate/Epoxy/Beam Plate as a unique “laminate shell” where each layer has its own properties. There …
Formulas for BC in shells and solids are essentially the same.
By "cylindrical directly" I mean that there is formulation already developed to see the results in cylindrical coordinates without having to transform anything. Just put the pipe cente…
Hi Drudland,
Welcome.
Yes , you can do it .
There are many references on the forum about it.
Imposing the radial and circumferential displacement boundary condition is the only tricky part.
You need to impose the displacement to each node on the…
Hi ,
UU and VV would have more sense for me if they are parallel and perpendicular to the weld.
This way they will provide information about the evolution of the Normal and Shear Stress along the weld. If you are using triangles for example or you …
You can also reorient the U and V local axis for the elements of interest before solving. This is done in element Mesh --> element properties. This way you can save some post processing and math.
It happend also to me. I had to solve again once the table is created for the set to appear.
I'm using mecway 13.1 and ccx 2.17.
Regarding selecting nodes shared by two perpendicular shell elements, i'm not sure what uu, vv and uv means. Thats p…
Hi JRP ,
I'm glad to see you found a workaround.
You just need to give a name to the set of nodes. In your case you named them Weld 1, so it directly appears when creating a new table in the solution tree. See image.
The only drawback is that nod…
That’s because ccx expands the beam element into a solid element. Each node becomes 4 nodes. Before solving give to the node, a name into the Named selection tree. Once solved you can add a new table int the Solution tree by right click > New tab…
HI JRP,
I don't think any structural software include the welding details on the FEM model.
They just extract the forces and moments to be further introduced in the connection model.
They have a huge connection library waiting for the forces and …
Hi,
¿By path plot do you mean Stress Linearization.?
In that case this option is available in Mecway.
Go to the GUI Tree > Solution (Right Click) > New Stress Linearization.
Good morning Victor,
I thought the word "Support" was reserved to define the behavior of the model with respect the outside. From my point of view, you are imposing additional constrains not requested between the elements of the model.
Beams: Whe…
Looks really advanced. That's a complete new level for me. as I do not have programming skills.
Let us know if you get some progress.
Your name is MANUEL. ¿Are you Spanish? ¿Are you student?

One thing that it is important gwillis,
When you say: "If the other degrees of freedom are not specified (4-6? rotations around x,y,z axes?) as you have done...."
-I have not specify anything around x,y,z axes. I have stablished a relationship be…
Not sure I understand your question,..
If two beams share a node, the software automatically consider the connection as rigid. (Same displacement and same rotation of both beams at that point)
If you separate the beams without any node in comm…
Buckling Load
Loading conditions have been changed as load is now applied to the web.
887KN ccx against 822KN Internal Solver. Without 100N
872KN ccx against With 100N
To be fair the 100N should be applied incrementally as 100*t. (*)
First mode…
Find example with arbitrary loads on the beam and free to rotate.
Just need to keep in mind that Pinned means same node displacement and rigid same displacement plus same rotation.
In this case, for large deflections I would go to nonlinear analisys…
Hi,
I would draw independent beams not sharing any node and impose the link through constrain equations on the vertical displacement for example.
See attached file. 1 uz3 - 1 uz8 = 0
Where 3 and 8 are the corresponding nodes at the connection p…
