Hello,
I'm doing 2-way FSI simulation in "fake" 2D (one cell in y direction). I'm modeling a musical instrument, in which a thin brass sheet vibrates in an air flow. My meshes are enclosed: https://www.dropbox.com/s/dxtdlq0vxkstdgs/air.png?dl=0 https://www.dropbox.com/s/v91y9c61qw...brass.png?dl=0 In the full 3D case in the module "System Coupling" i'm getting 100% of nodes mapped everywhere, but in "fake" 2D in Data Transfer from air to brass these values are very poor: https://www.dropbox.com/s/lva0n857mu...pping.png?dl=0 Changing meshes, which have quite good quality, have only very small effect. What can be the cause? Best regards, Bartosz Żłobiński |

PS
In Debug Level 2 i'm getting for Data Transfer from air: Code:
Mapping Controls (Conservative Aglm.): DBG | Tolerance : 0.1 DBG | Pixel Resolution : 100 | Data Transfer 2 | | | Percent Nodes Mapped | 15 10 | | Percent Area Mapped | 10 10 | Code:
Mapping Controls (Profile Preserving Aglm.): DBG | Tolerance : 1e-06 DBG | Edge Tolerance : 0.05 DBG | Tolerance Option : 0 DBG | Enforce Tolerance : 0 DBG | Bucket Scale : 50 | Data Transfer | | | Percent Nodes Mapped | N/A 100 | DBG | -- DBG | Badly Mapped Target Nodes (0): |

Solved!
Answer is simple: cell dimention in y-direction have to be very small. |
