When I import mesh in openform and change U and P after run in icofoam during run after some steps it generate error that error is :....................

Greetings to both of you.

I've merged your two threads since you're basically asking the very same question... 23 minutes apart.

The answer is simple - go read the cavity tutorial once again, starting from this section: 2.1.5 Increasing the mesh resolution
And keep reading the rest of the tutorial until you understand what needs to be modified

Best regards,
Bruno

Thanks & Regards,

Quick answer: Please read subsection "2.1.5.4 Control adjustments" on the OpenFOAM User Guide: http://www.openfoam.org/docs/user/cavity.php
