1. New CalculiX discussion group

   

   by prop_design · August 2020

   there was a useful post there about version 2.17. guido is saying the PaStiX solver is up to 4x faster than the Intel MKL Pardiso solver. also, if you have nVidia graphics card with CUDA support that

2. Calculix (CCX) 2.17 is out

   

   by prop_design · July 2020

   there looks to be some interesting new developments, in version 2.17:

3. Position dependent loads

   

   by German · July 2020

   Is it possible to include in a future version more position dependent loads?

4. Simple bolt modelling

   

   by Victor · July 2020

   Sorry for the frustrating crash. I'm not sure quite why it happens but I'll fix it for the next version (14).

5. Bolt Assembly Example

   

   by prop_design · June 2020

   imported the *.vol files. the mecway built in version is having problems. this makes setting up everything a lot harder, but at least it works.

6. Bolt Assembly Example

   

   by prop_design · June 2020

   Below is the latest version of the files. I made some updates to the standalone bolt file and the Mathcad file. The difference from bolt calculators is around 3-8 depending on single part or assembly,

7. Bolt Assembly Example

   

   by prop_design · June 2020

   here is the latest version. once i changed the stiffness for all contact inputs to '1.2e4 GPa/m' I also changed the plate materials. The goal was to bolt an aluminum plate to a stainless steel plate.

8. Library list order

   

   by Victor · June 2020

   The order is unspecified and might be something to do with the file system. I'll change this to alphabetical order in version 14. Thanks for bringing it up.

10. Max shear stress on shell eles

    from results. Please add this in the next version. The thing about the pressure could be an option or labs extra.

11. Mecway13 and Multi-threaded CCX

    

    by Victor · May 2020

    Those mistakes in the build process mentioned above are corrected in the current version of Mecway (13.1). Please don't use the CCX build script or instructions in v13.0 because they're so bad.

12. Version 13.1

    A bugfix update is now available here https://mecway.com/download that includes these fixes:

14. calculix 2.16 buckling problem??

    

    by Victor · April 2020

    There are two "versions" of CCX 2.16. An older one and a newer one. The differences are:

15. Mecway13 and Multi-threaded CCX

    

    by prop_design · April 2020

    at one time, i asked victor about the latest version of pardiso. on the pardiso website, they claim it is even faster than the older version in the intel mkl. i don't know if intel had a falling out w

16. Mecway13 and Multi-threaded CCX

    

    by prop_design · April 2020

    both methods you ask about use the same pardiso version in the intel mkl. the bolt assembly was something i made for a forum user, to try and show how to apply a bolt load. someone else started using

17. Mecway13 and Multi-threaded CCX

    

    by tk1537 · April 2020

    I ran the bolt file donated as a benchmark previously, and got roughly the same execution time for the previous pardiso version vs the ccx_MKL version.

18. calculix 2.16 buckling problem??

    

    by Stefanos · April 2020

    I think calculix 2.16 (at least the version for win32bit that I use with mecway9) omits to calculate or miscalculates the lowest buckling modes when acr<1 (I am aware of the shift point concept

19. How to create a sub-model?

    

    by JohnM · April 2020

    Models must have only volume elements, model and submodel must be same CCX version. If that's not the problem, I would try running in 2.10 or 2.11, to see if it's a new bug, other than that, it's tim

20. Mecway13 and Multi-threaded CCX

    

    by Sergio · April 2020

    Is there a reason why is not readily available an out of core MKL version of CCX?
