ForCAD v0.13.0 Released

[Ali]

I’m happy to announce that ForCAD v0.13.0 has been released.

Highlights:

• Improved performance of B-spline basis evaluation and derivatives

• Reduced allocation overhead by checking array sizes before reallocation

• Entire library uses pure procedures (except export routines)

• Parallelization with do concurrent

  • All tests and examples are run with the following compiler flags:
  • ifx: -qopenmp -fopenmp-target-do-concurrent
  • nvfortran: -stdpar=multicore,gpu
  • gfortran: -fopenmp -ftree-parallelize-loops=n
  • flang: ?
  • Best performance is observed with the latest Intel compiler (ifx).

• VTK export now supports optional point data and field names

• Added CMake support

• Added 2D and 3D IGA Poisson solver examples:
  poisson_iga_solver_2d.f90, poisson_iga_solver_3d.f90

• Added B-spline least-squares fitting in 1D, 2D and 3D:
  lsq_fit_bspline_1d.f90, lsq_fit_bspline_2d.f90 and lsq_fit_bspline_3d.f90

Feedback and contributions are always welcome!

Thanks again to @rwmsu for providing forIGES.

Looks awesome, congrats! If you haven’t submitted it yet to FortranCon 2025, I think you should.

Thanks a lot @milancurcic! I really appreciate the encouragement. I haven’t submitted anything to FortranCon 2025 yet, but that’s a great idea. Thanks for the suggestion!
