• @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?

• 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/

• 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 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

  in Mecway PC benchmarks Comment by 3rav September 2020
• 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.
