Hello Everyone,
Below is my POV file
1 union{
2 box{<0,0,0>,<1000000,1,1000000>}
3 box {<250000,1,450000>,<350000,10000001,550000>}
4 box {<740000,1,495000>,<750000,10000002,505000>}
5 pigment {color rgb <1,0,0>}
6 }
I have the following questions.
1) I need to apply Dirichlet Boundary conditions to face ymax of Box in line
3 and a different Dirichlet condition to face ymax of Box in line 4. Is it
possible in ff3d to apply boundary conditions by specifying a plane by
co-ordinates rather than ymax. If so how can this be done? Box in line 4 is
slightly larger than Box in line 3. Also if I specify the BC at ymax does it
apply the condition on the global ymax of the geometry ( in this case it
would be y=10000002) or does it apply it to the local ymax at each point of
the geometry?
2) As you can see my numbers are very large so I'll need a very fine mesh.
Will such numbers cause any numerical errors while transferring from POV to
ff3d?
