Member Function Documentation

void getfem::mesh_im::update_from_context ( void  ) const

virtual

this function has to be defined and should update the object when the context is modified.

Implements getfem::context_dependencies.

Reimplemented in getfem::mesh_im_cross_level_set, and getfem::mesh_im_level_set.

Definition at line 27 of file getfem_mesh_im.cc.

void getfem::mesh_im::set_auto_add ( pintegration_method  pim )

inline

Set the im for automatic addition of element option.

pim=0 disables the automatic addition.

Definition at line 68 of file getfem_mesh_im.h.

void getfem::mesh_im::set_integration_method	(	size_type	cv,
		pintegration_method	pim
	)

Set the integration method of a convex.

Parameters

cv	the convex number
pim	the integration method, typically obtained with getfem::int_method_descriptor("IM_SOMETHING(..)")

Definition at line 49 of file getfem_mesh_im.cc.

void getfem::mesh_im::set_integration_method

(

pintegration_method

ppi

)

shortcut for

set_integration_method(linked_mesh().convex_index(),pim);
and set_auto_add(pim)

Definition at line 75 of file getfem_mesh_im.cc.

void getfem::mesh_im::read_from_file

(

std::istream &

ist

)

Read the mesh_im from a stream.

Parameters

ist	the stream.

Definition at line 154 of file getfem_mesh_im.cc.

void getfem::mesh_im::read_from_file

(

const std::string &

name

)

Read the mesh_im from a file.

Parameters

name	the file name.

Definition at line 197 of file getfem_mesh_im.cc.

void getfem::mesh_im::write_to_file

(

std::ostream &

ost

)

const

Write the mesh_im to a stream.

Definition at line 205 of file getfem_mesh_im.cc.

void getfem::mesh_im::write_to_file	(	const std::string &	name,
		bool	with_mesh = false
	)		const

Write the mesh_im to a file.

Parameters

name	the file name
with_mesh	if set, then the linked_mesh() will also be saved to the file.
