Insert an external geometry (stl file) as a floating object

nava

Hi, I want to mimic the example of Casefloating. But, I want to put an airfoil as a floating object and not a box. I have the geometry of the airfoil in a stl file. When I run the xml as a result appears:
*** Exception
Text: A boundary particle was excluded
What may be wrong ?
Best Regards,

This is my xml








dp | real | bound



solid






bottom | right | front | back







void

sorry this is my xml

Please read first the following FAQ: http://dual.sphysics.org/index.php/forums/#q12

As shown in the validation of floatings at http://dual.sphysics.org/index.php/validation/wavesfloatings/
correct behaviour is achieved when using objects full of particles.

The guide also explains this in detail.

I have tried to fill the airfoil with boundary particles using the option fillbox but it didn't work. Must I first draw the airfoil by using the option drawfilestl and then use fillbox to fill it with particles? What is the criterion to choose the appropriate seed point concerning option fillbox?

"Must I first draw the airfoil by using the option drawfilestl and then use fillbox to fill it with particles? " OBVIOUSLY YES

Seed point should be an internal position inside the object of course
