Hi!

I get the error message 'Cell in couple is undefined', while I have defined these cells... What does it want from me?

Thanks,

Julie

Not all of them. Collapsed cell faces left, but I don't really know what to do with them, because I need triangular prismatic cells in my model.

cfix command can fix some or all of them. If the rest are ghost cells , you can just delete them without losing anything because they sit between well connected cells.

to get rid of collapsed cell faces, do a: cset news prism vset news cset vmer vset check cset,,facecollapse,news cflip cset,,,prism

This is probably the same as cfix, but you could try it

the easy way to solve your problem is to delete the couples all together and generate them again if you think the cells are there. If the cells have been gone what do you need these couples for ?

OK. Thanks to overall help I've fixed all the errors and... got an error that I've fixed already 3 times at least. It claims that I have couple with partial boundaries turned on that contains both fluid and solid cells. I know exactly that I created these couples as arbitrary with partial boundary turned off. It's just impossible!
