Well, usually people use \section to divide a chapter into sections (2.1., 2.2., 2.3. etc). You can of course change the numbering a bit: \renewcommand{\thesection}{\arabic{chapter}.\alph{section}}.
The smart way: Calm down and take a deep breath, read posts and provided links attentively, try to understand and ask if necessary.

Dear Johannes_B,
My query is how to devide chapter in sub chapters for my thesis. The chapter into sections 2.1, 2.2 etc are coming but I need two parts like chapter 2a and 2b after that the section. I am using following for sub chapters but in the section part previous chapter numbering coming (chapter 3a, 3b then in section part 2a.1, 2a.2 and 3a.1, 3a.2 etc are coming). How I tackle the problem?

  1. \newcounter{subchapter}\renewcommand{\thesubchapter}{\alph{subchapter}}
  2. \makeatletter
  3. % \patchcmd{<cmd>}{<search>}{<replace>}{<success>}{<failure>}
  4. \newcommand{\updatechaptercounter}{}
  5. \patchcmd{\@chapter}{\@afterheading}{\updatechaptercounter\@afterheading}{}{}% Regular patch of \@chapter
  6. %\patchcmd{\Hy@org@chapter}{\@afterheading}{\updatechaptercounter\@afterheading}{}{}% Hyperref patch of \@chapter
  7. \makeatother
  8. \providecommand{\theHchapter}{}%
  9. \newcommand{\startsubchapters}{%
  10. \setcounter{subchapter}{0}% Reset sub-chapter numbering
  11. \renewcommand{\thechapter}{\arabic{chapter}\thesubchapter}% Update chapter number display
  12. % \renewcommand{\theHchapter}{\arabic{chapter}\thesubchapter}% Update chapter number display (for hyperref)
  13. \renewcommand{\updatechaptercounter}{\addtocounter{chapter}{-1}}% Update chapter number
  14. \let\oldchapter\chapter%
  15. \renewcommand{\chapter}{\stepcounter{subchapter}\oldchapter}% Increment subchapter
  16. }
  17. \newcommand{\stopsubchapters}{%
  18. \renewcommand{\thechapter}{\arabic{chapter}}% Reset chapter numbering
  19. \renewcommand{\theHchapter}{\arabic{chapter}}% Reset chapter numbering (for hyperref)
  20. \let\chapter\oldchapter% Restore regular \chapter command
  21. \renewcommand{\updatechaptercounter}{}% Clear chapter counter update
  22. \stepcounter{chapter}% Update chapter counter
  23. }
