couples issue
 

Hi there,

I want to create couples in fluid and solid cells. The problem here is that there is some partial overlapping at some cells. So the couple check gives error messages (partial overlapping) while writing geometry file. I have checked other checks independantly and all are ok. Is it ok if I write geometry file without check?

Kindly guide if anybody faced similar problem.

- Thanks

well, as far as i know, partial boundaries between fluids and solids are not permitted.

if you run the case (if it is possible) then have a look at flow field around these corner. i would expect some unexpected behaviour.
