[tgrid] duplicate nodes - not really
 

Hello everybody,

I am having a problem in tgrid, it suggests to merge duplicate nodes where there are none.

Imagine a small cube and big cube having contact on one plane, like:


As indicated there are three faces, A,B,C and for some peculiar reason the mesh on A and B should be different, both A and B being walls in the geometry. So for A and B I have 8 line segments, in pairs of two having identical coordinates, which may by chance have boundary nodes with same coordinates. How can I tell tgrid to ignore the "duplicate" nodes?

Thanks in advance

George

I am facing a similar problem if some one could help us
