error 74 chec concerning cracks

July 19, 2006, 11:03

I created a mesh, whose I assembled from 2 grids, one flat and another one curved.

After all the setup, I checked the mesh and I have this error: error#74 CHEC there are cracks (unconnected regions) in the model.

What does it mean? And how can I fix the problem.

Dear friend,

when you are conecting two different meshes which dont have one to one nodel conectivity you have to create couples (integral or arbitrary couple) inbetween them to ensure proper connectivity. After creating proper couples check the model you will not have any cracks.
