[ICEM] solid surface or wireframe, who do I trust?

RCruz · April 4, 2019, 05:21

Hi!

Context :
Being a bit new to ICEM, I'm tasked with making watertight a plane geometry generated by ICEM from a CAD file.
Needless to say, ICEM does the best it can but a lot of small connectivity problems arise.

Problem :
I don't know how to confirm if the geometry is watertight since the surfaces match in wireframe view but they don't in solid view. When I Create/Modify curve > extract curves from surfaces the curves also seem to be watertight, but I know the software may not create a surface that perfectly follows the curve if there is approximation problems.

Example :

Here, there is a hole between blue and dark black surfaces, but the wireframe and curves merge correctly, so who do I trust?

Maybe the solution in this link:

Mesh is leaking (hole) at trailing edge of wind turbine blade
