- To generate a conformal mesh, first execute a global collapse of the model.
...
- The GiD collapse depends upon the Import tolerance. Two entities are collapsed (converted into one) when they are separated by a distance less than the Import tolerance parameter. To test this, enter a new value for the Import tolerance parameter.
...
- Go to Utilities->Preferences, and select Import and Export branch. Set the Import tolerance to User define value and enter 0.15 for the Value of import tolerance. Click Apply.

Some of the contiguous surfaces in the interior of the model have now being joined. However, there are still some surfaces that prevent the mesh from being completely conformal. These surfaces must be modified manually.
