[GiDlist] Problem with quadratic9 tiangles

[Andrea Calaon]

Hi GiD team,
I think I've found what is actually making GiD crash in
meshing:

the modified mesher of GiD 7.5.6b cannot handle a triangular
structured mesh with the Quadratic9 option on surfaces.

Cordially,

Andrea

Hello,

I have some problems to mesh a structure composed of 2 pependicular
NURBS surfaces in contact as shown on view1.gif.

I wish the mesh to be "continued" from a surface to the second other.
That means that there are some common nodes on the NURBS line common to
the 2 surfaces.

But, whenever I mesh the structure I have got 2 meshes that are not in
contact (see view2.gif).

I suppose that I forget a special action to obtain one mesh.

If somebody used to mesh in this way I would be very interested by an
advice.

Thank you in advance.

The geometry topology is reflected in the mesh topology.
Your surfaces are unconnected (don't share any boundary line), then the
nodes are not shared.

You must split the bottom surface with the line (menu:
Geometry-Edit-Divide-Surface-Split)
but the end points of the splitting line/s must be connected with the
surface to split !!

Before use it, can intersect all lines (menu:
Geometry-Create-Intersection-Multiple lines)
