Hi all, I am doing heat transfer analysis using time dependent solver. At end how to get the temperature value at each nodes for a particular time step ?.

Hi
COMSOL does not give you the values on the "nodes", as such, but will give you the values along a line, surface, point or around the volume=domain. These entities can be predefined in the geoemtry, or defines as virtual planes lines points and then the postprocessor interpolates the values it has around to "project" onto the desired entity.
You must think slightly differently, ths is inded disturbing when you come from other "traditional" FEM programmes, but after a while you will find it more logical, and better in line with a math versus physics separation of model analysis.
It's the same for "4-node or "10-node" thets mesh elements (older way), this is neither so in COMSOL, you talk about thet mesh elements and interpolation functions, linear or quadratic or cubic or ...

Good luck
