How to avoid Failed Meshing in condition of small interspace between Models?
 

Hi everybody, I am currently doing a cfx simulation about aerodynamic parts of racing car.
In my model there is a small interspace between main body shell and end plate of front wings, which I think is the reason why failed meshing happens.
I have tried different settings of mesh(sizing,inflation). all failed. I have done all simulations of every single part(main body, front wings,rear wings etc), the meshing are perfect, no such problem. It seems this problem only happens in the case with assembly parts.
Do you guys know how to avoid this mesh problem if i keep the model like this? Or do you guys have ever similar experience?

increase the tolerance of interface

thanks for your answer Kapi, i have tried a loose Model tolerance in DM and increasing the Max Face/Tet Size, Min Size and Defeaturing Tolerance in Sizing of Meshing. It seems not work. Did I do something wrong?

i normally do it in CFX model when i create my interface.
I just change face search tolerance factor and it takes into consideration.
By default its 1

thanks Kapi, i solve this problem.

did you use the solution which I provided or used some other solution?
If you have used other solution then please post it here, it will someone who has similar problem!

I change the size of the Element and Angle, the number of total elements is going big, but it is a good meshing already.
