Member Function Documentation

◆ set_auto_add()

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.

◆ set_integration_method() [1/2]

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(..)") getfem::int_method_descriptor pintegration_method int_method_descriptor(std::string name, bool throw_if_not_found=true) Get an integration method from its name .
