FEM Calculator

1D bar, beam, heat and spring finite-element models

About this tool

Small 1D and Euler–Bernoulli beam models assembled from 2-node elements. Pick a preset, set geometry and material data, then compare FEM nodal values with closed-form checks where available.

Setups

  • Axial bar — fixed at one end, tip force or uniform axial load.
  • Heat bar — fixed temperature at one end; fixed T or flux at the other.
  • Cantilever beam — fixed displacement and slope at the base; tip point load or UDL.
  • Simply supported beam — zero deflection at both ends; UDL.
  • Spring chain — identical springs in series.

Increase element count to approach the analytical solution. Reaction forces at constrained nodes are reported.
