The length of the rod is 0.5 m. calculate the steady state temperature distribution in the rod. take thermal conductivity of rod is 1000 w/m/K. the diameter of the rod is 10 cm. The governing equation for the above problem is d/dx(kdT/dx) = 0; 1) my question is how to solve one dimensional problem in openfoam 2) which solver is suitable for the above problem 3) what modification should i do for the above problem thank u in advance.

Hi,
You can use scalarTransportFoam solver neglecting the convection and transient part. It's easy, and basic solver

Then set your left and right patches to fixedValue of the temperature you want. Hope it helps, Philip skuznet likes this. Last edited by bigphil; August 24, 2012 at 12:24. Reason: typo
