  I find it solves with CCX_PARDISO.exe 2.17 dated "niedz., 26 lip 2020 19:57:20" but not with the default CCX.exe 2.17 included with Mecway dated "Wed Jun 16 14:14:29 2021".
  
  It may be too big.

  using the v2.18 ccx_dynamic.exe file from the ccx website, the pastix solver completed in 4min 35sec, using 3 cores. i have 16gb of memory. the von mises stress is shown below.

  keeping the solvers up to date is a moving target. there are several threads on the forum talking about it. everyone's setup is different unfortunately.

  @victor , @prop_design
  
  It really worked by changing the calculix version as indicated.
  
  as I'm not familiar with programming, I found a compiled version on the calculix forum but not optimized for my PC [since it used only one core], replace it in the mecway folder and everything worked.

  I will install the libraries and try to better understand how to optimize it.
  
  Thank you very much
