Interfaces

VTK_VAR

Procedure for saving data variable(s) in VTK-legacy standard.

VTK_VAR is an interface to 8 different functions, there are 3 functions for scalar variables, 3 functions for vectorial variables and 2 functions texture variables: scalar and vectorial data can be R8P, R4P and I4P data while texture variables can be only R8P or R4P. This function saves the data variables related to geometric mesh. @note The inputs that must be passed change depending on the data variables type.

Examples of usage

Scalar data calling

 integer(I4P):: NN
 real(R4P)::    var(1:NN)
 ...
 E_IO=VTK_VAR(NN,'Sca',var)
 ...

Vectorial data calling

 integer(I4P):: NN
 real(R4P)::    varX(1:NN),varY(1:NN),varZ(1:NN)
 ...
 E_IO=VTK_VAR('vect',NN,'Vec',varX,varY,varZ)
 ...

Functions

VTK_DAT

Function for initializing/finalizing the saving of data associated to the mesh.

Function that must be called before saving the data related to geometric mesh, this function initializes the saving of data variables indicating the type (node or cell centered) of variables that will be saved. @note A single file can contain both cell and node centered variables. In this case the VTK_DAT function must be called two times, before saving cell-centered variables and before saving node-centered variables.

Examples of usage

Saving node data

 E_IO=VTK_DAT_XML(50,'node')

Saving cell data

 E_IO=VTK_DAT_XML(50,'cell')
