Can anyone help me in this matter. How can I write the equation as attached using comsol as I need to determine the time using integral equation below which x = distance in x direction and v = velocity simulated using incompressible navier stokes mode. Thank you in advance. Tue, 09 Mar 2010 16:16:43 +0000 3692.1268151403.9596
