Using The Non Conformal Resulting Mesh Type
Non-conformal imprinting provides a way to imprint parts efficiently without spending time imprinting CAD parts conformally when it is unnecessary.
Simcenter STAR-CCM+ allows you to imprint parts non-conformally. This process is useful when:
- a conformal interface is not necessary to achieve solution accuracy
- there are many contacting parts
- each part is within many pairs
- there are gaps between the CAD parts
During the process of non-conformal imprinting, pairs of split surfaces are created on contacting parts without altering the individual parts or creating shared faces.
The following geometry shows two parts that are in close proximity with a small gap between the surfaces.


To achieve a non-conformal mesh when imprinting these surfaces, before you imprint the parts, activate Show Advanced Parameters and set Resulting Mesh Type to
After imprinting the parts, the resultant surfaces are non-conformal, which means that the surface discretization on the imprinted surfaces does not match. Each part remains separate and there is no shared surface between each part. However, the original discretized surfaces are cut and a pair of split part surfaces are created which represent an in-place part contact between the surfaces.


Taking a closer look at the pair of split surfaces, you can see that the surface discretization on each split part surface is non-conformal:


The in-place part contact which represents the pair of split part surfaces appears in the simulation tree:
