5. NL Static 3D - Bolt Connection with Preload

   

   by hooshsim · March 2019

   1. I am trying to model/analyze a bolt connect assembly to predict stresses around the blade holes. In your simplified version you have removed all the bolts/nuts and that's representative of my model

6. NL Static 3D - Bolt Connection with Preload

   

   by prop_design · March 2019

   i took a look at your model. i attached a very simplified version. this is along the lines of what i was saying earlier of just fixing the washer faces. i wasn't sure of a lot of what you setup, so i

7. NL Static 3D - Bolt Connection with Preload

   

   by prop_design · March 2019

   oh i didn't see you attached the model. id love to try it as well. i model similar things. ansys workbench is really good for retention modelling, cyclic symmetry, bolt loads, and contact. but i got t

8. WARNING in usermpc: no MPC is generated for the mean rotation in node

   

   by Victor · March 2019

   The next version of Mecway (12) will have elastic support for CCX so you won't need to make the new element or material.

9. Gmsh v 4.2.1 fails

   

   by tk1537 · March 2019

   I just tried Gmsh v 4.2.1 (latest release) and it fails with an error "adjacent nullptrs found". I have been using v 4.1.5 successfully, but this new version doesn't appear to work. Has an

10. Version 11

    

    by Victor · February 2019

    I've reproduced the problem that the ccx.exe 2.15 on dhondt.de can have obvious random errors with modal vibration (*FREQUENCY) that the single-threaded version included with Mecway doesn't. Here is a

12. Version 11

    

    by tk1537 · February 2019

    Victor, Here's the text from the CCX output file for the problem I ran on your v.11 with the embedded CCX. Do you intend to test the multicore version against the problem areas you mentioned? I'd b

13. Version 11

    

    by Victor · February 2019

    Yes. The CCX from dhondt.de is compiled for multicore but the one with Mecway isn't. I'm surprised it still does that with stiffness and stress though. The multicore versions usually fail more test ca

14. Version 11

    

    by Victor · February 2019

    Once the download page is updated to show version 11, it won't change without the version number changing too.

16. Shell Elements With CCX Are Solid In Results

    

    by Nekativ · February 2019

    My bigger question is how is Mecway Internal handling this to where I can view the 2D version of the elements in the results and get stresses that are still accurate/not underestimated.

17. Brittle Failure in Laminates

    

    by Victor · December 2018

    The demo version has no missing features except being limited to 1000 nodes. It doesn't have any CCX convergence options in the UI but you can enter the CCX card for that (*CONTROLS) in CCX ->

18. Brittle Failure in Laminates

    

    by lpdotcom · December 2018

    BTW I'm using the demo version - does the full version have the ability to change convergence tolerance for the CCX NL Dynamic solver?

19. CalculiX 2.15 - New version

    

    by Sergio · December 2018

    Today I found that a new version of CalculiX is avaliable, 2.15, both for Linux and Windows

20. Version 10 beta

    

    by Eduart · December 2018

    I'm not sure if this is te right place for request for the new version but could it be possible to rename the loads and constraints (as is by the named selections?) Would make life much easier in cas
