Any analytical solutions for intersecting line heat source in a domain ?

10 October 2018 1 4K Report

As I would study the singularity problem at the intersection of line heat source, so I wonder if anyone know any analytical solutions for the problem with intersecting line heat source in a finite/infinite domain? Really appreciate it!

Try, the book, Heat conduction using Green's Functions. J.V. Beck. I guess do you find it there.

How to determine if a type of element suffers from locking or not in FEM?

I designed a new 2D FEM element, so I want to know if it suffers from locking or not, so I wonder is there any numerical value or methods with which I can know the answer. Thanks for your answering.
