TinyGismo.jl

Welcome to the documentation of TinyGismo.jl, a Julia interface to the G+Smo (Geometry + Simulation Modules) library.

Overview

TinyGismo.jl provides comprehensive tools for:

  • Spline-based geometric modeling using B-splines and NURBS
  • Isogeometric analysis with basis function evaluation and refinement
  • Parametric curves, surfaces, and volumes for CAD and scientific computing

Key Features

  • Univariate and tensor product B-spline bases
  • NURBS (Non-Uniform Rational B-Spline) support with weights
  • Knot vector manipulation and refinement
  • Geometric evaluation, derivatives, Jacobians, and Hessians
  • Factory functions for creating standard shapes
  • File I/O for reading and writing geometric data

Quick Start

using TinyGismo

# Create a knot vector
knots = [0.0, 0.0, 0.0, 0.5, 1.0, 1.0, 1.0]
kv = KnotVector(knots)

# Create a B-spline basis
basis = BSplineBasis(kv)

# Create a simple rectangle
rect = createBSplineRectangle(0.0, 0.0, 1.0, 1.0)

# Evaluate the geometry at a point
u = [0.5, 0.5]
out = gsMatrix{Float64}(2, 1)
eval!(rect, u, out)
