Reply To: How to create 2D triangle ？
Thanks for your recommendation. But I have to incline a 2d cuboid of the whole geometry, which was created by 2 cubiod (one is parallel to the axis, the other has to be inclined). That geometry was similar to the example aorta3d model.
In my case, the deltaX was equal to the width of the inclined cuboid dividing the resolution N (35). I do not know why the number of outflow materials was just 3 when setting the inclined outlet, while the vertical outlet was normal.
