input of point coordinate

Please login with a confirmed email address before reporting spam

Hi,
i'm working with a cylindrical model and it's important I mesh it via the swept method.
The problem is that I need an electrical point source somewhere inside my cylinder and the "mesh daemon" isn't too happy about it.
I was wondering if was possible to select a point of the mesh on the image and get the coordinates. In this way I will attribute to the electrical point source this coordinates.
This is a little trick i thought. now with the questions:
1) Is it possible to grab the coordinates graphically?
2) If it is, the procedure that i want to use could cause some " hidden" problems ?
thank you all a for your time,
Giorgio.

Hi

try to cut your geoemtry such that the "point is some clever intersection of lines oredges of a boundary, then normally you can mesh with a sweep , AND catch the point. Normally you cannot go backwards from mesh to geoemetry in COMSOL, as the mesh is based on the geoemtry and not the inverse

Good luck

Thanks ivar, but i already tried that, i didn't mange to do it...
olus I'm looking for something at a higher level compared with the mere research of a line with my face close to the monitor because the point must be as close to a surface inside the cylinder as possible....
i'll find another way, thanks,
Giorgio

Hi

And it's true that I cannot find back the "revolve mesh" feature of 3.5, probably not yet implemented in V4
