  • @FERNANDO If you can, compare ccx_2.20+MFront vs ccx_2.21+MFront with Drucker Prager
    in ccx + MFRONT Comment by 3rav February 26
  • It is possible that due to the lack of these: librarieslibgcc_s_seh-1.dll, libwinpthread-1.dll, libstdc++-6.dll, MFront with the Mecway or PrePoMax could not work (bconverged has these libraries in the bin folder). https://calculix.discourse.group/…

  • Does your analysis work with regular material (not MFornt, but e.g. *ELASTIC)?
    in ccx + MFRONT Comment by 3rav January 12
  • @FERNANDO Since this is a dynamic version, do you have the mkl/PARDISO libraries connected?
    in ccx + MFRONT Comment by 3rav January 12
  • Hi, Have you tried GNUPLOT? like: fit f(x) 'data.txt' via C10, C01, C20, C02 ,C11
  • Since the ccx source code is official on github (https://github.com/Dhondtguido/CalculiX), can you add yours "out-of-core" option for PARDISO solver via pull request?
  • Please test this version: https://calculix.discourse.group/t/calculix-and-pastix-solver-windows-version/130/42?u=rafal.brzegowy
  • Hi, I have a few questions for these results: 1. What libraries of MKL, PARADISO requires on your computer? 2. Was pastix with the flag: PASTIX_MIXED_PRECISION=1 (and OPENBLAS_NUM_THREADS=1)? I am a bit surprised by the difference between pastix …
  • "When using 16 or 32 threads PastiX works but runs super slow." See this: https://calculix.discourse.group/t/calculix-and-pastix-solver-windows-version/130/18?u=rafal.brzegowy
  • @prop_design I have the same symptoms as I did not copy all the necessary oneAPI dll library. In my case (Haswell) ccx need: libiomp5md.dll mkl_avx2.1.dll mkl_core.1.dll mkl_intel_thread.1.dll and most important: mkl_rt.1.dll
  • @MikeMcMullen At the moment, it cannot be done due to the error: https://github.com/msys2/MINGW-packages/issues/6923 https://sourceforge.net/p/mingw-w64/bugs/886/
  • Hi, Try this, option "modify keyword", select *STATIC: SPOOLES PARDISO PaStiX
  • For ccx 2.18 I changed from "Dynamic" to "Single Dynamic Library", from: https://software.intel.com/content/www/us/en/develop/tools/oneapi/components/onemkl/link-line-advisor.html Base description (http://portal.nacad.ufrj.br/online/intel/mkl/commo…

  • 1. Install base needed packages: $ pacman -Sy mingw-w64-x86_64-toolchain $ pacman -Sy make 2. Install packages needed for CalculiX: $ pacman -Sy mingw-w64-x86_64-openblas $ pacman -Sy mingw-w64-x86_64-spooles $ pacman -Sy mingw-w64-x86_64-arpack 3…
  • The Windows version does not support GPU computing due to the lack of nvcc (CUDA -> only nvidia) compiler in the mingw environment (msys2). It is possible that in the future GPU support will be possible thanks to StarPU with OpenCL (AMD, nvidia a…
  • You can dowload ccx from (CalculiX forum: https://calculix.discourse.group/t/calculix-and-pastix-solver-windows-version/130/16?u=rafal.brzegowy) https://www.dropbox.com/s/zd7fj0ceaj8j44n/CalculiX.7z?dl=0 This archive contains the ccx version linke…
  • You only need one ccx.exe file, but linked to these 3 solvers and run it with the command (in the .inp file): *STATIC,SOLVER=SPOOLES or *STATIC,SOLVER=PARDISO or *STATIC,SOLVER=PaStiX for (from ccx 2.17 manual): *BUCKLE, *COUPLED TEMPERATURE-DIS…
  • Try: set PASTIX_MIXED_PRECISION=1
  • Hi, Important, for the best possible performance on PaStiX, set: set OPENBLAS_NUM_THREADS=1 use only for physical processors (set OMP_NUM_THREADS= max physical cores) Please try with this settings.
  • Please remember that this version dosen't have Parsec
  • Please check: https://calculix.discourse.group/t/calculix-and-pastix-solver-windows-version/130/2
  • CPU: Intel Core i7-4800MQ @2.7GHz 4 core 8 threads RAM: DDR3 32GB @3500MHz Run times: 1. Intel MKL: 1 min 53 s (best of 3 test) 2. PARDISO Project 6.0: 2min (best of 3 test)
  • May I ask anybody to generate .inp file (full) of this test case.

  • Hi kwip, How did you use openblas to compile ccx? Regrads
    in CCX 2.13 Comment by 3rav December 2017
  • Try GNUPLOT - example Equations from https://www.code-aster.org/forum2/viewtopic.php?id=13908
  • That's right. Defining material: *MATERIAL, NAME=@CALCULIXBEHAVIOUR_ELASTICITY@2 *USER MATERIAL, CONSTANTS=2 200000,0.3 It would be nice if Mecway had such a library at the start with a few materials (Drucker-Prager, Johnson-Cook, Chaboche). Rega…
