Using Industrial Computed Tomography

Using Computed Tomography data for simulations​


In the course of digitalization, simulation is taking on an increasingly important role in component development. Some development steps in the area of physical tests can be replaced or supplemented by their virtual counterpart. Simulations help to reduce costs, increase safety or shorten the development process. But the quality and the results of a simulation depends strongly on the input data.​


A CT of a part can be used as „real world“ basis for a simulation. In VGSTUDIO MAX it is possible to generate a volumetric mesh of the entire scanned part including internal information like porosity, local fiber orientation, fiber to volume fraction, or local porosity. These analysis results can be mapped directly on the mesh cells. The material information can now be used along the real geometry of the scanned part as start parameter for a simulation. This workflow also allows simulation of parts, without having a CAD model available.​


Improve simulation accuracy (by using real-world fiber orientation)

In some cases the predicted fiber orientation from process simulation is different to the orientation within the real components. Using CT data this deviation can be identified and corrected in order to have valid assumptions for further simulation steps like in FEA (Finite Element Analyzes) and also to improve the accuracy of the predicted fiber orientation from process simulation.

Using porosity information in simulation​

When generating a volumetric mesh it can be decided if the internal porosity is taken into account as geometry or as local value for single mesh cells.​

Using Geometry information for simulations​

Geometry information can be used in simulations using a volumetric or a surface mesh, depending on the usecase. Both mesh types represent the real geometry of the scanned part.​


By using the measurement capabilities of VGSTUDIO MAX on simulation results, the evaluation of the simulated and the real part is done in a consistent way throughout the product life cycle, allowing objective results at any time.​

CT and 
fluid simulation​

Especially for CFD simulation the exact shape of the object is crucial, because small deviations can have huge effects on the result. Normally the real part is not represented 100% by the CAD model. To avoid influences on the simulation results the geometry directly generated from the CT scan can be used. ​
