**v4.24.201** TTNP201 -Heat transfer with time-dependent conductivity
===============================================================================

**Summary:**

This test consists in imposing a conductivity that varies as a function of time during a heat transfer. An imposed flow condition is applied to one edge of the wall and on the opposite edge the temperature remains constant. Conductivity increases over time and a temperature jump is observed on the edge where the flow is imposed.

The problem is addressed in PLAN, AXIS, and 3D.

The reference solution is obtained by the Crank-Nicholson iterative method.

The consideration of conductivity as a function of time is tested.
