Re: Stress Result in a cylinder Shell

Running the same model on calculix directly and displaying the results using cgx the results are as expected. I guess this is just some typo in the way results are imported from the datasets. Could you please confirm this? Jake you would have to share the FC file for us to judge the issue. Deleting...

Thanks. I'm fighting my way up the learning curve.

Re: Stress Result in a cylinder Shell

How stable is the next candidate? For FEM very much better than 0.17. There where fixed lots of issues. I do not even have 0.17 installed anymore (would install it only if someone would find a bug we really would need to fix still in 0.17 release, but we did not have this in 0.17 release cycle ... ...

Re: Stress Result in a cylinder Shell

(*STATIC -> *BUCKLE) We should think about adding this buckling stuff to FreeCAD as an analysis type ... Based on the 0.17 version I had quite a list for improvements, but I'm positively surprised on the advances since 0.16; if the improvements in 0.18 are similar this will be quite a good tool. I ...

Re: FEM – Sandwich Panel Buckling

@HarryvL, thank you for the contribution. Could you perhaps submit the .inp file for the buckling calculation? I'm just starting to use freeCAD and Calculix hoping to solve mainly linear strength and buckling problems. I have extensive experience with ANSYS Classical and I'm not afraid of getting m...

Re: Stress Result in a cylinder Shell

Hello @bernd, Thanks for the prompt answer. I tried to attach the FreeCAD files but they were too large. What is the limit? How can I send larger files? I use 0.17 as being a beginner using the stable release seems to be the right choice ;-) How stable is the next candidate? Is there some informatio...

Stress Result in a cylinder Shell

Dear all, Mighty work, thank you all for your efforts. When modelling a simple cylinder with external pressure on it, I think I got some qualitatively wrong results, namely: when requested to display the max principal stresses (PS1), the stresses shown are the SXX components. On the attached fig the...
