plane creation

Postby simonz » Thu Apr 07, 2016 7:54 pm

Hi:
I've looked the tutorial but still confused about how can i create a plane, which composed by quadratic tetrahedron for simulating a particle drops on it (say the plane is along the x-z plane)?

Thanks a lot

I don't understand well your question.

In preprocess, a plane is a geometrical surface, that require its boundary lines and points.
You can create a surface in different ways: from its boundary lines, from the copy window by extruding some line (by translation, rotation, etc), with a specific tool like geometry->create->Object
e.g. you can create a circular surface in the x-z plane setting the normal along the y axis (0,1,0) and selecting also its center and radius

In postprocess you can do a cut of the visible mesh by a 'virtual plane', defined for the cut with 3 points, or two points and normal to the current user view direction.
e.g. a cut of a tetrahedra mesh will create a new set of triangles on the cutting plane.
