[Other] toposet only working when origin is inside the defined zone in the box

lmw354 · August 4, 2021, 03:06

Hello

I have created a mesh using blockmesh and i am trying to split the regions using toposet. But toposet is not showing any cells unless origin is inside the defined region.

in my geometry there is a cylinder with its center on x axis at distance equal to the circle's radius from origin

When the cylinder definition in toposet is equal to radius (touching origin) then it is detecting elements

When i reduce the cylinder radius by 1mm it is showing 0 elements

i am new to openfoam please help
Thank you in advance

Never mind

i was using scale 0.001

but apparently i have to write the lengths in mks itself. now its working
