substitutes of "boxToCell" and its application
 

Hello,
when geometry is complex, what are the substitutes of "boxToCell"?
regionToCell, zoneToCell, shapeToCell?
could someone give 3 simple examples of how to use the above 3 as follows as with "setFields"?


thank you in advance





an application example of "boxToCell" in OF-tutorials:
---------------------------------------------------------
boxToCell
{
box (0 0 0) (40.0 1.0 0.4046);
fieldValues
(
volScalarFieldValue alpha.water 1
);

---------------------------------------------------------

btw. I also re-posted this thread in the pre-processing block.

sorry for wrong place



thanks

With searchableSurfaceToCell, you could specify an arbitrary enclosing surface "blob" (eg, an stl) and select based on that. In fact, since it is backed with a searchable surface, you could even specify using a searchable surface that is a box and it would be the same as boxToCell. You probably don't want to do that, but may be nice to know

thank you, olesen for the reply.

I gonna have a look in detail to see if i still get question.


in between

thanks and regards
