I am solving the 2D heat conduction problem in Ansys. I am unable to increase the number of nodes. First for creating the 3 elements and 8 nodes in a component of length 3m and height 1m. I select mesh control > edge sizing. After selecting the left and right edges, I go to geometry and push the apply button. Then, under type>number of division. I give the number of divisions as 1. And, it provides me with the required mesh. As shown
Then, for my next problem, I have need of 6 elements along x-axis like the previous example and 14 nodes like this.
But, when a change the condition and increase the number of divisions to 3. It generates such a mesh.
It not only increase the number of the element along x to 9 but, also increases the number of nodes and element by providing 2 more extra horizontal lines in the middle of the component. I am a student of Fundamental of the FEA course and my many colleagues are facing this issue regarding increasing the number of nodes. Therefore, I have created this thread. I will be very thankful, I someone figure out our problem and guide us on how to generate a mesh with 6 element and 14 nodes in 2d_ steady-state heat conduction problem. Thank you. If anyone has need of some more details for clarification than feel free to ask. Furthermore, if I increase the number to division to 6 as stated in the mesh refinement screenshot, then the condition is even worse like that.
I have attached the file also if it is helpful for someone.

Use face meshing.
Combined with "Hard" behavior for edge sizing.
btw which license are you using?

Thank you very much @Aniket. First, I applied face mesh to the whole body. Then, by choosing to sizing in the mesh control and selecting the top and the bottom surface I got my mesh. I reduce the size to 0.5m for getting 6 elements in the total length of 3m.
I am using version Ansys 19.2. Thanks for solving my problem.
