Thanks for the info mmartin, but with such details my calculations will get too complicated. I agree that this is possible with one flange and a tube. But if you want to design a machine, this is too much work and also too much unknowns...

Let say that we have two plates welded toghether. Something similar as disla posted. I would like to get to normal and both shear stresses on the plates contact. With that I can specify the welds. https://www.researchgate.net/figure/Level-of-stress…

Ok. Thanks for this info. Unfortunately, I have some problems with type of elements and loads. If I use CCX, then I can't use line pressure on line3 elements.
-
Ok. I get it. Thanks for this. But if I understand corectlly this is only available with solid elements? I have most of the models built from shell elements. I'm looking for something like that.
-
Forget question number 2. I checked again and I saw that maximum under UU are the same as under points 1 and 3.

Hello again with one question regarding stress output in beams. I attached a LIML file and few screens from Mecway. I'm doing stress calculation for a simple tripod and I question the maximum stress output. 1) If I understand correctly UU stress r…

Hello Andrea, Here it goes. Check my screenshots for more info. It looks like there is some sort of bug in FreeCAD. When you go to preferences, you can't see tabs for STEP and IGES settings for export and import. 1) Open STEP file first. 2) Go to …

Yes, I usually use google for all my forum searches. You just need to use specific site search, like: "mecway shell mesh site:http://mecway.com/forum"

Nice video VMH. I'm sure it will be useful for other user. A proposal maybe for Victor to create some sort of database of these videos and other things that are not all written in manual. It is hard to search for them on the forum when you don't kno…
-
That's great VMH. It works. Thank you for your time with making the video. Which software do you guys use for screen video filming? I had to change one setting in FreeCAD, because it did a compound merge at import of original STEP file and I had on…
-
Ok. I thought so. Thanks for answer.
-
Hello VMH, I've tried your solution, but it seems I get it wrong somewhere, because I get the same result. I import my STEP model to FreeCAD and then select whole geometry. I press union command and I get error shown on screenshot. After that I ge…
-
Thanks Andrea very much for your time and effort. I will try this and report back soon.
-
Thanks for answers. Let me explain in some more detail how I break all the surfaces already in CAD (Solidworks). There are two possibilities: 1) You make separate surfaces with intersecting (NOT SAME) edges. If you can join these edges together, th…
-
Is there anything new on importing surfaces to Mecway as STEP model? I'm still having problems with not being able to join all the surfaces together in Solidworks into one surface. I then save it as STEP model and when I import it to Mecway and mes…
-
Ok. I will check it out and see... Thanks. Is there anyway to define axes during element definition? Something like which node is selected first?
-
I see now. But disla showed me reversed z axes of elements, so that they are all pointing out of the ring. With inverse command we inverse only x and y axes, z remains the same.
-
That doesn't work for me. What am I doing wrong?
-
@ Victor: Ok. I've checked the formula definition. That will be useful in the future. I will try and see what other options can I get out of that. Thanks... @ disla: I agree, but it is not practical to have so many materials defined in complex calc…
-
Ok. Thanks. I will check it out and see. Talk back soon...
-
Ok. Good again. Thanks. But as I can see it is only possible for point 1, 2, 3 and 4 and not for "stress UU". Do you have any examples for manipulating with plots with formula tool for beam elements?
-
Ok. That's good. But that is possible only graphicaly. I can't select a node and check stresses there, because we have 4 possible points. It would be great if it could be possible to sum normal + bending stresses and show them as maximum plot. That …
-
Ok. Thanks for answer.
-
Thanks Victor, I will check it out and maybe post some questions later if this project comes to realization.
-
Thanks. Will take a closer look at options that table can give me.
-
Ok, I see. But where can I find this table?
-
Hey Victor, Thank you for answer. I got it. One question more though. Is it possible to get reaction forces components for global coordinate system?
-
Ok. Thanks. Didn't notice it before. It will make some things easier now.
-
Yes, the node values are positive, I checked. I can check it with better resolution, thanks for info. In which version was the cutting plane introduced? I can't find it in version 4. As of separating results - that would be great. I'm always thi…
-
Here are some detailed screenshots with resolution set to highest value. I forgot to mention that I'm working with shell offset - half the thickness of the tube. I use this because it is a lot more work to create offset surfaces with CAD software. I…
