template<int N, typename T >

void EulerianComm< N, T >::computeFaceCentroids

(

)

Compute the face centroids.

Call this after wait_mesh() if you will use the face centroids.

template<int N, typename T >

void EulerianComm< N, T >::computeFaceNormals

(

)

Compute the face normals.

Call this after wait_mesh() if you will use the face normals.

template<int N, typename T >

virtual void EulerianComm< N, T >::initializePressure

(

)

[pure virtual]

Initialize the pressure at the nodes or the faces.

This function should be called after wait_mesh() and before accessing the pressures.

This function is implemented in the derived classes.

Implemented in EulerianCommBoundary< N, T >, and EulerianCommShell< N, T >.

template<int N, typename T >

void EulerianComm< N, T >::receiveMesh

(

const Number *

domain

)

[inline]

Post receives for the relevant portions of the mesh from the solid processors.

Parameters:

domain

is the region of interest for this fluid processor.

This function just calls the above receive_mesh(const BBox& domain).

template<int N, typename T >

void EulerianComm< N, T >::receiveMesh

(

const BBox &

domain

)

Post receives for the relevant portions of the mesh from the solid processors.

Parameters:

domain

is the region of interest for this fluid processor.

template<int N, typename T >

virtual void EulerianComm< N, T >::sendPressure

(

)

[pure virtual]

Start sending the pressure to the relevant solid processors.

Call this function after the pressures have been set.

Implemented in EulerianCommBoundary< N, T >, and EulerianCommShell< N, T >.

template<int N, typename T >

void EulerianComm< N, T >::waitForMesh

(

)

Wait for the receives to complete. Build the assembled mesh.

This function must be called before accessing the mesh.

template<int N, typename T >

virtual void EulerianComm< N, T >::waitForPressure

(

)

[pure virtual]

Wait for the pressure sends to be copied into communication buffers.

This function must be called after send_pressure().

Implemented in EulerianCommBoundary< N, T >, and EulerianCommShell< N, T >.
