Intersecting surfaces when thickened

Hi everyone,

 

I´ve encountered a problem when using hypermesh. I have imported and meshed a wing that has the following shape:

<?xml version="1.0" encoding="UTF-8"?>general.pngclose.png

The problem appears in that sharp line, because when the laminte is created, it intersects in this point. Here is a picture:

The cad file is made out of one only surface, so the problem should not be there. In a previous try with the cad made of two faces the same problem appeared, and when simulating I found out the surface was split through that edge. Here the picture.

<?xml version="1.0" encoding="UTF-8"?>separate.png

So I am afraid I am going to have the same problem once again with the model of only one surface. 

The possible sources of error that I can figure out are the model, the messing or the creation of the laminate. This last one actually looks like this:

So I would be very grateful if anyone could tell me what things could be made to solve the problem I have.
