Question on "refinement" option in "Pre-Mesh Params"
 
Hello,

i have a quick question regarding refinement. When i set the level value to 0.5, i receive an error message stating "factor must be positive." The ICEM Help states the following:

"A Level value greater than 1 will result in refinement, while a Level value less than 1 will result in coarsening of the pre-mesh"

From this statement, a value of 0.5 would result in a coarser mesh. Am i missing something? Is there another way to coarsen selected blocks? Thanks,

john

I don't know why this gave you a hard time... Have you figured it out? (I know I am way late, but Christmas is a busy time ;^)

Try "1/2" instead.

Thank you!
You made my day.
The manual tells you to enter a value less than 1 for coarsening, but you can't enter a value less than 1.
Never would have thought of entering 0.5 as 1/2.
