Detailed Description

Base virtual class of Flow123D application.

Contains base methods of application for initialization, run and finalization which is used in derived class.

Usage:

class Application : public ApplicationBase {
public:
  Application(int argc, char ** argv); // constructor
protected:
  virtual void run(); // implementation of pure virtual method
  virtual void after_run(); // overriding of parent method
}

Constructor & Destructor Documentation

ApplicationBase::ApplicationBase ( int  argc, char **  argv  )

protected

Constructor

Construction is done in init method. We need to call virtual methods during construction.

Definition at line 70 of file application_base.cc.

ApplicationBase::~ApplicationBase ( )

protectedvirtual

Destructor.

Definition at line 203 of file application_base.cc.

Member Function Documentation

virtual void ApplicationBase::after_run ( )

inlineprotectedvirtual

Execute part of program after run of simulation.

Method can be override in derived class.

Reimplemented in Application.

Definition at line 134 of file application_base.hh.

Here is the caller graph for this function:

void ApplicationBase::init	(	int	argc,
		char **	argv
	)

Contains basic structure of application (initialization, run and finalization). Method is call after constructor and allows to call virtual methods.

Definition at line 184 of file application_base.cc.

Here is the caller graph for this function:

virtual void ApplicationBase::parse_cmd_line ( const int  argc, char **  argv  )

inlineprotectedvirtual

Parse command line parameters before Flow123D initialization.

Method can be override in derived class.

Reimplemented in Application.

Definition at line 110 of file application_base.hh.

Here is the caller graph for this function:

int ApplicationBase::petcs_finalize ( )

protected

Finalize PETSC. If finalization failed return nonzero value.

Definition at line 164 of file application_base.cc.

Here is the caller graph for this function:

void ApplicationBase::petsc_initialize ( int  argc, char **  argv  )

protected

Implement printf function for PETSc with support for redirecting. Initialize PETSC.

Definition at line 139 of file application_base.cc.

Here is the caller graph for this function:

virtual void ApplicationBase::run ( )

protectedpure virtual

Run application.

Method must be implemented in derived class.

Implemented in Application.

Here is the caller graph for this function:

void ApplicationBase::system_init ( MPI_Comm  comm, const string &  log_filename  )

protected

Read system parameters, open log.
