HOPR Output Parameter

Parameters Example Data Type Default Value Description
Array Dim.
Debugvisu Debugvisu=T LOGICAL F T (True): Files will be generated, which enable you to visualize the mesh and the boundary mesh for debugging. These files can be found in the directory of the executed parameter.ini file.

F (False): Files for visualization will not generated during executing of the parameter.ini file.

DebugvisuLevel DebugvisuLevel=1 INTEGER 0 0: Visualization of linear mesh and BC (default).
1: Visualization of linear mesh and BC and an additional curved surface visualization (_SplineSurf.*) if useCurveds=T.
2: Visualization of linear mesh and BC and an additional curved volume visualization (_SplineVol.*) if useCurveds=T.
NVisu NVisu=5 INTEGER 0 Number of visualization points per element edge if useCurveds=T.
outputFormat outputFormat=1 INTEGER 0 0: Paraview vtk (ASCII)
1: Tecplot (ASCII)
2: CGNS (binary)
ProjectName ProjectName=cartbox STRING OBLIGATORY Part of the output files' name which will be generated during the execution. These Files can be found in the directory of the executed parameter.ini file.

A description of all parameters of the parameterfile can be found in List of Parameters.

Recommended Settings

ParaView is susceptible for defective output visualizations in cases of using high order meshes or increasing the polynomial degree of supersampling. For this reason, it is recommended to edit several settings to get a correct high resolution visualization. At first the way of projection should be changed. Therefore, go to Edit > View Settings ... (Picture 1) and activate use parallel projection (Picture 2).

If the polynomial degree of supersampling is higher than 1 the mesh elements will be subdivided depending of the polynomial degree. As a result, it is not apparent anymore where the elements begin and where they end. Because of that two filters have to be applied which make the actual elements visible again in high resolution.

Custom Filter HO-visualization

For simplifing and accelerating this visualization prozess of the HOPR output a custom filter named HO-visualization is provided. This custom filter converts the steps of filter selection to a single step prozedure. After the custom filter was created it has to be imported into ParaView. Therefore, go to Tools > Manage Custom Filters ... (Picture 6), click on Import and add the custom filter HO-visualization (Picture 7).

Once the filter is imported it appears in the alphabetically sorted list of the filters (Picture 8)

and can be selected (Picture 9).
