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

Thank you for kind answer.

Yes, it is watertight.

When I use option 2, openLB shows worse performance than 1. It cannot identify the small pipe, and material 3, 4, 5 are all not recognized.

Happily, I get the good geometry with option 5, except matarial 3 is not resolved. I follow totally same procedure to assign material 3 with 4 and 5. But, the indicator of material 3 does not work properly. I already several checked my code, but I cannot find any mistakes. I hope you also have comments for this material assignment problem..

Anyway, your answer makes really big improvement. So appreciate your comment.
