2. Upload geometry¶
The starting point of a topology optimization workflow is the definition of the design space.
This space must be described by an existing volumetric geometry in STEP format, respecting the following criteria:
supported CAD formats are STEP AP214,
the CAD must contain only non-overlapping volumes/solids; i.e. a water-tight shell is not valid,
1D wires or 2D surfaces are not supported, and
the model will be assumed to be in millimeters (mm).
The geometry can contain coloured faces - which will create an initial group of face sets - and distinct (non-overlapping) volumes which can be the target of different volumetric conditions.
The geometry can be uploaded using a single STEP file (.step or .stp) either through the upload button or by drag-and-dropping the file into the highlighted area described in the following Upload geometry panel image.
