# OS-V: 0110 One Dimensional Transient Heat Transfer

Test No. T3 OptiStruct examines the material temperature at point C, 0.08m from point A and the total simulation time is 32 seconds for transient heat transfer analysis.

## Benchmark Model

The 2-noded beam elements, Quad4 elements and Quad8 elements are used to build the model with 5 elements each for the coarse mesh and 10 elements each for the fine mesh. At time t=0, all temperature = zero and at time t>0, at one end temperature is zero and at the other end temperature is 100 sin(πt/40) °C. There is no heat flux perpendicular to the length of the beam.
