info

This example shows how to initiate an instance of Mesh by reading data from mesh file, which is in HDF5File_ format. We will also construct an instance of STVectorMeshField_.

PROGRAM main
  USE easifemBase
  USE easifemClasses
  IMPLICIT NONE
  TYPE( HDF5File_ ) :: meshfile
  TYPE( Mesh_ ) :: amesh
  TYPE( STVectorMeshField_ ) :: obj
  TYPE( ParameterList_ ) :: param

Step 1:

Initiate and open the mesh file which is in HDF5File_ format.

CALL meshfile%Initiate( FileName="./mesh.h5", MODE="READ" )
CALL meshfile%Open()
CALL amesh%Initiate(hdf5=meshfile, group="/surfaceEntities_1" )

Step 2:

Initiate an instance of STVectorMeshField_.

CALL FPL_INIT(); CALL param%initiate()
CALL SetSTVectorMeshFieldParam( &
  & param=param, &
  & name='aVector', &
  & varType = Constant, &
  & fieldType=TypeField%normal, &
  & engine='NATIVE_SERIAL', &
  & defineOn=Nodal, &
  & nns=6,  &
  & nnt=2 ,  &
  & spaceCompo = amesh%GetNSD())
CALL obj%Initiate( param=param, mesh=amesh)
CALL obj%Display( 'obj: ' )

The above code will initiate an instance of STVectorMeshField_, which will contain following data.

Object INITIATED: TRUE
name: aVector
prefix: STVectorMeshField
fieldType: NORMAL              
engine: NATIVE_SERIAL
tSize: 484
defineOn: Nodal
rank: Vector
varType: Constant
shape: 
-------
   2   
val ALLOCATED: TRUE
mesh ASSOCIATED: TRUE

Let's try to understand the above situation:

In above call (internally) we have saved data in a two-dimensional array val.
The number of rows in val for above example is 1.
Because, we have set varType=Constant, all nodes (we have specified 6 nodes in space and 2 nodes in time) in an element have same value of vector field. Read more about the Shape method.
The number of columns in val is 484, which is same as the total number of elements in the mesh. This is because we have used fieldType=normal in the above example.

Step 3:

  CALL obj%Deallocate()
  CALL amesh%Deallocate()
  CALL meshfile%Close()
  CALL meshfile%Deallocate()
  CALL param%Deallocate(); CALL FPL_FINALIZE()
END PROGRAM main

  TYPE( Mesh_ ) :: amesh
  TYPE( STVectorMeshField_ ) :: obj
  TYPE( ParameterList_ ) :: param

Step 1:

CALL meshfile%Initiate( FileName="./mesh.h5", MODE="READ" )
CALL meshfile%Open()
CALL amesh%Initiate(hdf5=meshfile, group="/surfaceEntities_1" )

Step 2:

Initiate an instance of STVectorMeshField_.

CALL FPL_INIT(); CALL param%initiate()
CALL SetSTVectorMeshFieldParam( &
  & param=param, &
  & name='aVector', &
  & varType = Constant, &
  & fieldType=TypeField%Constant, &
  & engine='NATIVE_SERIAL', &
  & defineOn=Nodal, &
  & nns=6,  &
  & nnt=2,  &
  & spaceCompo = amesh%GetNSD() )
CALL obj%Initiate( param=param, mesh=amesh )
CALL obj%Display( 'obj: ' )

The above code will initiate an instance of STVectorMeshField_, which will the contain following data.

Object INITIATED: TRUE
name: aVector
prefix: STVectorMeshField
fieldType: CONSTANT            
engine: NATIVE_SERIAL
tSize: 1
defineOn: Nodal
rank: Vector
varType: Constant
shape: 
-------
   2   
val ALLOCATED: TRUE
mesh ASSOCIATED: TRUE

Let's try to understand the above code:

We save data in a two dimensional array val.
The number of rows in val for above example is 1. This is because the vector data is constant in space and time inside the element. Because, we have set varType=Constant, all nodes (we have specified 6 nodes in space and 2 nodes in time) in an element has constant value. Read more about the Shape method.
The number of columns in val is 1, this is because the fieldType=Constant (i.e., constant across all the elements).

Step 3:

  CALL obj%Deallocate()
  CALL amesh%Deallocate()
  CALL meshfile%Close()
  CALL meshfile%Deallocate()
  CALL param%Deallocate(); CALL FPL_FINALIZE()
END PROGRAM main

info

This example shows how to initiate an instance of Mesh by reading data from mesh file, which is in HDF5File_ format. We will also construct an instance of STScalarMeshField_.

The mesh is given below

PROGRAM main
  USE easifemBase
  USE easifemClasses
  IMPLICIT NONE
  TYPE( HDF5File_ ) :: meshfile
  TYPE( Mesh_ ) :: amesh
  TYPE( STScalarMeshField_ ) :: obj
  TYPE( ParameterList_ ) :: param

Step 1:

Initiate and open the mesh file which is in HDF5File_ format.

CALL meshfile%Initiate( FileName="./mesh.h5", MODE="READ" )
CALL meshfile%Open()
CALL amesh%Initiate(hdf5=meshfile, group="/surfaceEntities_1" )

Step 2:

Initiate an instance of STScalarMeshField_.

CALL FPL_INIT(); CALL param%initiate()
CALL SetSTScalarMeshFieldParam( &
  & param=param, &
  & name='aScalar', &
  & varType = Space, &
  & fieldType=TypeField%Normal, &
  & engine='NATIVE_SERIAL', &
  & defineOn=Nodal, &
  & nns=6, nnt=2 )
CALL obj%Initiate( param=param, mesh=amesh )
CALL obj%Display( 'obj: ' )

The above code will initiate an instance of STScalarMeshField_, which will contain following data.

Object INITIATED: TRUE
name: aScalar
prefix: STScalarMeshField
fieldType: NORMAL              
engine: NATIVE_SERIAL
tSize: 484
defineOn: Nodal
rank: Scalar
varType: Space
shape: 
-------
   6   
val ALLOCATED: TRUE
mesh ASSOCIATED: TRUE

Let's try to understand the above code:

We save data in a two dimensional array val.
The number of rows in val for above example is 6. This is because we have set varType=Space, which means the scalar data changes in Space inside the element. Note that the data does not change in time in an element.
Because, we have set varType=Space, therefore val(1:6) denotes the value of scalar field at 6 nodes of element. Read more about the Shape method.
The number of columns in val is 484 (which is the total number of elements in the mesh), this is because the fieldType=Regular (i.e., changes across all the elements).

Step 3:

  CALL obj%Deallocate()
  CALL amesh%Deallocate()
  CALL meshfile%Close()
  CALL meshfile%Deallocate()
  CALL param%Deallocate(); CALL FPL_FINALIZE()
END PROGRAM main

Step 2:

Initiate an instance of STScalarMeshField_.

CALL FPL_INIT(); CALL param%initiate()
CALL SetSTScalarMeshFieldParam( &
  & param=param, &

  & nns=6, nnt=2 )
CALL obj%Initiate( param=param, mesh=amesh )
CALL obj%Display( 'obj: ' )
call display(amesh%GetTotalElements(), "total elements: " )

The above code will initiate an instance of STScalarMeshField_, which will contain following data.

Object INITIATED: TRUE
name: aScalar
prefix: STScalarMeshField
fieldType: NORMAL              
engine: NATIVE_SERIAL

defineOn: Nodal
rank: Scalar
varType: Time
shape: 
-------
   6   
val ALLOCATED: TRUE
mesh ASSOCIATED: TRUE
total elements: 484

Let's try to understand the above code:

We save data in a two dimensional array val.
The number of rows in val for above example is 6. This is because we have set varType=Time, which means the scalar data changes in Time (and remains constant in space) inside the element.
Because, we have set varType=Time, therefore val(1:6, iel) denotes the value of scalar field at 6 time-nodes of element. Read more about the Shape method.
The number of columns in val is 484 (which is the total number of elements in the mesh), this is because the fieldType=Regular (i.e., changes across all the elements).
