[snappyHexMesh] bounding box: searchableType

student666 · July 14, 2014, 11:18

Hi all,

I can't understand why SHM gives me trouble about the following Fatal error:

Code:

Illegal bounding box specification : (-0.165 -0.3922 -0.087) (-0.235 -0.2172 0.0875)

I verified into the CAD file that coordinates are correct and define the bounding box, for refinement, properly.

But If I set max all positive:

Code:

  min (-0.165 -0.3922 -0.087) max (0.235 0.2172 0.0875)

It works, but it's useless for me.

How can I define this refinementBox?

Think I found the solution to this dummy problem.

If anyone interested here the reason:

in the defintition of the bounding box, you're supposed to define as "min value" with minimum value for x, y, z at all; while max refer to maximum value for x, y, z at all.

eg:

Code:

refinementBox {type searchableBox; min (-0.235 -0.005 -0.165); max ( -0.165 0.005 0.01);}

works: x y z for min are < than max values

Code:

refinementBox {type searchableBox; min (-0.165 0.005 -0.165); max ( -0.235 -0.005 0.01);}

dosen't work as x y z for min are not < max value.

Hi,
Thank you very much for having written the solution of your problem. I was wondering myself !
