VTK Plugin
Overview
The VTK Data Provider Plugin has been developed using Data Provider Framework.
The provider can be plugged into applications based on HOOPS Envision for Desktop. This includes HOOPS Envision Demo Analyzer and the RemoteModel server (UgServer) in HOOPS Envision for Web. The same plugin can be used both on web and desktop.
The cdp_Vtk plugin provides the following data based on a given ModelKey:
- Meta data about the given model: Number of states (time increments), geometries (multiple domains + boundaries), results
- CAE model with elements and nodes
- Results: Scalar, Vector, Displacements and Tensors
- Element sets
The VTK data provider plugin will then be used to open all your .vtu, .pvtu, .pvd and .vtm files.
Available Options
The following options are supported by the VTK Data Provider:
| Name | Type | Default | Description |
|---|---|---|---|
| PVD_WELD_INTERFACE_NODES | bool | true | Weld interface nodes for pvd files. |
| PVTU_WELD_INTERFACE_NODES | bool | true | Weld interface nodes for parallel vtu files. |
| PVTU_PARTID_FIELD_NAME | string | PartID | Field name for Parts in PVTU files. |
| VTU_PARTID_FIELD_NAME | string | PartID | Field name for Parts in VTU files. |
| READ_VECTOR_AS_DISPLACEMENT | boolean | false | Read Vector as Displacements. |
| USE_CEETRON_ACCESS_COMPATIBILITY | boolean | true | HOOPS Access compatibility: i.e Use 6 components as SymTensor. Use 3 components as vector. Use Results Nature. |
| RESULTS_NAMES_MAPPING | string | U=VELOCITY;displacement=DISPLACEMENT;strain=STRAIN;strain_energy_density=STRAIN_ENERGY_DENSITY;stress=STRESS;pd=PRESSURE;T=TEMPERATURE;points=POSITION;origId=IDENTIFIER;rho=DENSITY;gamma=FLUID_PHASE;positions=POSITION;cellID=IDENTIFIER;scalars=SCALARS |
Changelog
VTK
Version 1.0.0 [December 2, 2025]
CSAM-1351 : VTK provider supports to read pvd files where geometry is partitioned into different vtu files for a given time step.
CSAM-1352 : Fixed an issue in the node welding feature of parallel vtu (pvtu) and pvd files. User can do following settings which are now supported by the Vtk Plugin.

Name : PVTU_PARTID_FIELD_NAME Type : string Default : PartID Explanation : Field name for Parts in PVTU files.
Name : PVD_WELD_INTERFACE_NODES Type : bool Default : true Explanation : Weld interface nodes for pvd files.
Name : VTU_PARTID_FIELD_NAME Type : string Default : PartID Explanation : Field name for Parts in VTU files.
