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}}.

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?

Code: Select all

\newcounter{subchapter}\renewcommand{\thesubchapter}{\alph{subchapter}}
\makeatletter
% \patchcmd{<cmd>}{<search>}{<replace>}{<success>}{<failure>}
\newcommand{\updatechaptercounter}{}
\patchcmd{\@chapter}{\@afterheading}{\updatechaptercounter\@afterheading}{}{}% Regular patch of \@chapter
%\patchcmd{\Hy@org@chapter}{\@afterheading}{\updatechaptercounter\@afterheading}{}{}% Hyperref patch of \@chapter
\makeatother
\providecommand{\theHchapter}{}%
\newcommand{\startsubchapters}{%
  \setcounter{subchapter}{0}% Reset sub-chapter numbering
  \renewcommand{\thechapter}{\arabic{chapter}\thesubchapter}% Update chapter number display
 % \renewcommand{\theHchapter}{\arabic{chapter}\thesubchapter}% Update chapter number display (for hyperref)
  \renewcommand{\updatechaptercounter}{\addtocounter{chapter}{-1}}% Update chapter number
 \let\oldchapter\chapter%
 \renewcommand{\chapter}{\stepcounter{subchapter}\oldchapter}% Increment subchapter
}
\newcommand{\stopsubchapters}{%
  \renewcommand{\thechapter}{\arabic{chapter}}% Reset chapter numbering
  \renewcommand{\theHchapter}{\arabic{chapter}}% Reset chapter numbering (for hyperref)
  \let\chapter\oldchapter% Restore regular \chapter command
  \renewcommand{\updatechaptercounter}{}% Clear chapter counter update
  \stepcounter{chapter}% Update chapter counter
}
