Multi solid interface mesh
 

Hello everyone,

I am a very beginner with Starccm+ and I try to mesh a multi solid geometry.
I read that I had to create an interface between the two solids to avoid this type of mesh at an interface between two solids :

But after I create this interface I don't know what is the procedure to make a smooth mesh at the interface between the two parts.
Do you recommend a tutorial to help me to do this ?
Thank you very much

Give same mesh values at interface surfaces. If you have not captured curves then do that first. Capture the part curves with default setting in geometry node and then assign these to region. This will mostly solve your problem.

Is this a wrapped geometry?
