01 Basics

This chapter is the best entry point if you want to understand how a jNO script is structured from domain setup through solving and plotting.

In This Chapter

• Laplace 1D

  The smallest end-to-end PINN example with hard Dirichlet boundary conditions.

  Walk through the example

• Poisson 1D

  A closely related problem that switches to soft boundary constraints and finite differences.

• Biharmonic 1D

  A fourth-order problem showing how hard constraints simplify higher-order PDEs.
