Reply To: The geometry in STL is not well recongnized in OpenLB

You can try the other modes of the STL reader (sorry for the hidden documentstion here, in the next release this will be an enum instead of integers).

enum class RayMode : int {
  FastRayZ  = 1,  /// Indicate function with ray in Z-direction(faster, less stable). Default option
  Robust    = 2,  /// Old indicate function (slower, more stable)
  FastRayX  = 3,  /// Indicate function with ray in X-direction(faster, less stable).
  FastRayY  = 4,  /// Indicate function with ray in Y-direction(faster, less stable).
  DoubleRay = 5   /// Indicate function with double ray
};

I recommend option 2.

The STL file is watertight?
