mayuresh0987 is on a distinguished road
Problem Statement:
I have to perform transient thermal analysis on a spherical flask which has 2 layers of insulation. To simplify the problem I neglected the cap portion of the flask and assumed it to be two whole concentric spheres.
My problem is that for conduction to occur, I would merge the two faces of insulation which are supposed to be in contact with eachother.
But when I try to use the merge feature of Ansys Design Modeller, It shows this error message:
" No valid mergeable clusters"
Pls help me.
