Hey guys,

I got a geometry in STEP-format and I imported it directly as a region in Starccm +. Then is splitted the geometry by patch to define several boundaries. After working and repairing the geometry I recognized that it is necessary to select the geometry from the Geometry tree to work with the Volumetric Controls.

So is it possible to translate my geometry from the Region tree (incl. Boundaries) to the Geometry tree and to maintain my defined boundaries so I can get them as parts? Or do I have to start a new simulation?

Thx

you can export the imported representation as a dbs file then import this file as a part

then delete the import representation and connect the part to the existing region

it is better to import the cad as iges since it retains the underlying geometry whereas the above technique gives you tesselated surfaces

if you use region based meshing you can use volumetric controls with you existing file but parts based meshing has lots of advantages

Thank you for your response.
I imported the .dbs file and connected the part with following steps to my existing region.

Parts < XY < Set region < XY

Hiow can I check if the connection to my region was succesful?

Thank you

clear your generated mesh and remesh - if something is missing you will get an error

but if every part surface is connected to a region boundary which you should first check then it should be fine

Thank you everything fine
