gogu, See YouTube video below. Results are close to hand calculations. Maybe mesh refinement may get the results closer or maybe not all loads are accounted for. Hope this help a little. Note: 1 N/mm^2 = 1 MPa. Files are attached if interested.

gogu, welcome to Mecway! I see a few possible problems with your model. First, the model doesn't match the provided data. The modeled diameter of the davit arm was 160 mm instead of 80 mm (see attachment). Also, it's best to use quadratic tetra…

IA-FEMesh seems to be able to hex mesh mechanical parts. Sergio, have you tried? What file export does IA-FEMesh offer? Can we import the mesh into Mecway for FEA? (Images attached from IA-FEMesh manual) Thanks
-
Sergio, very interesting works! I would do the same too for that application.
-
Sergio, I haven't tried bolts pretension. Just a thought: I dont really see a need for them unless doing slip critical connection where the connections can not allow to slip. But even with that, we can calculate the connection capacity with equati…

Updated YouTube video of Beam Clip Contact Test CCX in link below.

Ok. That's great! This will be very helfpul to connect parts together. Thanks!

Victor, please disregard my above comment. It's been requested.

Sergio, I used ActivePresenter which is free for noncommercial uses. I'm still looking for a better and clearer one that doesn't cost too much but haven't found one yet that is better than ActivePresenter n it's free. I do agree with your comment o…

See YouTube below for beam clip contact test.

Victor, is it possible to have bonded contact or something similar like "New Tied Contact (CCX Only)" to connect surfaces together (translation and rotation like bonded contact in Linear Static Analysis) for the nonlinear analysis running CCX? The …

kam33mitch, In addition to what Victor said above, I would use quadratic elements (with midside nodes) for solid elements subjected to bending to obtain more accurate results (It's usually recommended at least 3 to 4 layers thru the thickness whe…

kam33mitch, can you share your .step file for the base? Thanks

There are other CAD softwares like Inventor, Catia, Solidworks, etc but they cost alot. FreeCAD is just one of many CAD modeling softwares out there and it's free. The workflow for larger project is generally modeling in the CAD software --> exp…

Looking forward to the next release!

Attached are the files if anyone interested.

Victor, This new contact CCX only feature and your suggested initial value are great! I've been trying to this example for some time and your feature is very easy to use. See YouTube video in the link below. Thanks!
-
Thanks Victor. Would the next version has something like material CCX only simliar to the contact CCX only so we don't have to type them in again and again each time. In either case, I'm really hoping that components can be included in the results w…

Victor, would we see a side effect or odd solution if we use that in nonlinear type analysis with just 1 step instead of multiple step?

For a single node, you can't have more than two lines connecting to it. I just replicated the case with more than two lines connecting to a single and had the same message. Once I delete the third line, there's no more message. Your shape also nee…

NP. So far Mecway is the best out there for the price vs functions. Best wishes.

Victor, this feature probably not in the current version 4.0 yet, correct? I searched and couldn't find it.

Wow, there's a new feature (contact CCX only) I didn't realize (attached). This is nice!
-
Thanks. I usually add friction last too.
-
Yea. I also tried a few from bconverged calculiX beam contact examples. Adjusting the first coefficient to about 9 to 10 times the young modulus usually give a hard contact. Smaller values yield softer contact (with penetration). The hard contact t…
