Finite difference solutions only work for 2D Steady state co
     Finite difference solutions only work for 2D Steady state conduction problems with no heat generation.  True  False  Your 2D conduction problem is the same as Case 1 in Table 4.1. You need to know both the heat transfer rate, q, and the temperature distribution. Which is the best method to sol  problem?  Use a Finite Difference program to solve for both q and the temperature distribution. No checks are needed if you use a small grid size.  Use the shape factor in Table 4.1 to solve for both q and the temperature distribution.  Use a Finite Difference program to solve for both q and the temperature distribution, then check q against the answer from the shape factor in Table 4.1. 
  
  Solution
1-false it work for 3d also
2-use a finite difference programm to solve for both q and the temperature distribution then check q against the answer from the shape factor
