one dimensional conduction heat transfer simulation needed for a few configurations

I am looking for a one dimensional conduction heat transfer simulation for a cylindrical rod. I have a few material options in mind and the boundary condition should be constant temperature gradient. Part sizes are approx. 0.10" long by .020" diameter. If you are experienced in working on this type of project, please reach out to me and let’s discuss further details of this project. I am looking forward to hearing from you soon!
