Does anyone know the steady state analytical temperature field for a line heat source (or for multiple line sources meeting at a junction)?

I would like to get the analytical solution for a heat junction to investigate the singularity there. I think I can get the temperature field of a triple line heat junction by applying...

Can I get the displacement or stress field after knowing the singularity of a multiple material junction point?

I read some papers and then get the singularity at the junction point of multiple material assembly, can I use that to retrieve the field of the domain to later on used in a error calculation? If...

How to assemble a special line element with one dummy node (displacement is calculated by sum of another two nodes)?

A line element in FEM based method, one node of this line element doesn't retain any physical meaning, here I mean the displacement of that node is calculated by the linear combination of another...
