Not sure if this can help. I dont know if this depend on the regular geometry but maybe on the quality of the mesh that is not properly defined. i faced a similar problem . Check if the stl has interseting or duplicated elements , degenerated elements with areas equals to 0.
ciao francesco Quoting "Regine Schmidt" <[email protected]>: Dear all, I want to calculate the centerlines of a geometry I constructed by connecting tubes of different diameters (kind of an ideal bifurcation). Unfortunately, I always get the error message: "Unable to factor linear system". If I am calculating the centerlines for a real vessel-geometry (which I extracted from CT data) I have no problem at all. I guess this problem appears due to my regular geometry. I already tried Luca's advice from an older thread and added "-usetetgen 1", but then the program is just crashing. Is there any way to avoid this and to extract the centerlines?
