In the previous issue of CAE, we introduced the fact that the apparent deformation of a product can change depending on the way the reference is taken.
Why does this happen in the first place?
Usually, when conducting CAE, most models are in STEP/IGES format.
In this format, the model is dimensioned and the surfaces are not collapsed.
So the coordinate system can be easily created.
However, since the sled analysis needs to reproduce the deformation of the model, it is automatically converted from the STEP format to the STL format of the point cloud.
This means that the dimensions and surfaces that the model had will be destroyed.
In this case, there is no coordinate system or even a reference plane.
Therefore, it is necessary to create a virtual reference plane and define it as the reference plane.
Measurements are taken not only on the analysis but also on the actual molded product on a virtually created surface in the same way.
