Hi Vinayak, If you do not manually initialize member variables in a constructor, they are automatically initialized with their default constructor (i.e. one which takes no arguments). However, the FESystem class is such that the default constructor is manually deleted, and so can't be constructed without explicitly passing in some arguments. In order to get your code to compile, you'll need to call a non-default constructor for your FESystem member variable in the constructor of Network.
See the FESystem documentation or step-8 ( https://www.dealii.org/current/doxygen/deal.II/step_8.html#ElasticProblemElasticProblemconstructor) for an example of how to properly construct an FESystem object.
