Class BlockSolver

source code

Generic class for multi-dimensional (implemented with Block) sequential/parallel solvers. Meta, metric, and connectivity data arrays are absorbed into the instance of this class.

Before the invocation of init() method, bind() method must be called.

Note: When subclass BlockSolver, in the init() method in the subclass must be initilized first, and the super().init() can then be called. Otherwise the BCs can't set correct information to the solver.

Method Details [hide private]

__init__(self, blk, *args, **kw)
(Constructor)

source code 

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

Overrides: object.__init__
(inherited documentation)

bind(self)

source code 

Bind all the boundary condition objects.

Returns:
nothing
Overrides: BaseSolver.bind

Note: BC must be bound AFTER solver "pointers". Overridders to the method should firstly bind all pointers, secondly super binder, and then methods/subroutines.

boundcond(self)

source code 

Update the boundary conditions.

Returns:
nothing.

call_non_interface_bc(self, name, *args, **kw)

source code 

Call method of each of non-interface BC objects in my list.

Parameters:
  • name (str) - name of the method of BC to call.
Returns:
nothing

init(self, **kw)

source code 

Check and initialize BCs.

Overrides: BaseSolver.init

pull(self, arrname, inder=False, worker=None)

source code 

Pull data array to dealer (rpc) through worker object.

Parameters:
  • arrname (str) - the array to pull to master.
  • inder (bool) - the data array is derived data array.
  • worker (solvcon.rpc.Worker) - the worker object for communication.
Returns:
nothing.

pullank(self, ankname, objname, worker=None)

source code 

Pull data array to dealer (rpc) through worker object.

Parameters:
  • ankname (str) - the name of related anchor.
  • objname (str) - the object to pull to master.
  • worker (solvcon.rpc.Worker) - the worker object for communication.
Returns:
nothing.

pullibc(self, arrname, bc, sendn, worker=None)

source code 

Pull data from the interface determined by the serial of peer.

Parameters:
  • arrname (str) - name of the array in the object to exchange.
  • bc (solvcon.boundcond.interface) - the interface BC to pull.
  • sendn (int) - serial number of the peer to exchange data with.
  • worker (solvcon.rpc.Worker) - the wrapping worker object for parallel processing.

push(self, marr, arrname, start=0, inder=False)

source code 

Push data array received from dealer (rpc) into self.

Parameters:
  • marr (numpy.ndarray) - the array passed in.
  • arrname (str) - the array to pull to master.
  • start (int) - the starting index of pushing.
  • inder (bool) - the data array is derived data array.
Returns:
nothing.

pushibc(self, arrname, bc, recvn, worker=None)

source code 

Push data toward selected interface which connect to blocks with larger serial number than myself.

Parameters:
  • arrname (str) - name of the array in the object to exchange.
  • bc (solvcon.boundcond.interface) - the interface BC to push.
  • recvn (int) - serial number of the peer to exchange data with.
  • worker (solvcon.rpc.Worker) - the wrapping worker object for parallel processing.

unbind(self)

source code 

Unbind all the boundary condition objects.

Overrides: gendata.unbind
