[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:

Code:


+--------------+
|              |
|        C    |
|              | side view
+-----+        |
|    |        |
|  AB |        |
|    |        |
+-----+--------+
 
 
+--------------+
|              |
|              |
|              | top view
|              |
|              |
|              |
|  A      C  |
+-----+--------+
+-----+
|  B  |
|    |
|    |
+-----+


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
