error during meshing

Hello everyone,

Can you please suggest me how to solve intersecting face element error and failed to generate mesh for a particular domain ?
This is the error message am getting:
Finalized geometry has 21 domains, 188 boundaries, 390 edges, and 230 vertices.
Mesh error (ftet1): Failed to generate mesh for domain.
