I’m happy to announce that **[ForCAD](https://github.com/gha3mi/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`

- 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](https://github.com/gha3mi/forcad/blob/main/example/poisson_iga_solver_2d.f90), [poisson\_iga\_solver\_3d.f90](https://github.com/gha3mi/forcad/blob/main/example/poisson_iga_solver_3d.f90)

- Added B-spline least-squares fitting in 1D, 2D and 3D:  
[lsq\_fit\_bspline\_1d.f90](https://github.com/gha3mi/forcad/blob/main/example/lsq_fit_bspline_1d.f90), [lsq\_fit\_bspline\_2d.f90](https://github.com/gha3mi/forcad/blob/main/example/lsq_fit_bspline_2d.f90) and [lsq\_fit\_bspline\_3d.f90](https://github.com/gha3mi/forcad/blob/main/example/lsq_fit_bspline_3d.f90)

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!
