    Comsol-Shear stress with velocity profile

    Dear all, I was trying to calculate the shear stress due to fluid flow inbetween two parallel plates from the velocity profile taken from the middle of the flow channel (along vertical axis 'y') using comsol. The solution i got is two times the analytical solution i have calculated. The...

    Comsol-Fluid flow and shear stress

    Dear all, I was trying to calculate the shear stress due to fluid flow inbetween two parallel plates from the velocity profile taken from the middle of the flow channel (along vertical axis 'y') using comsol. The solution i got is two times the analytical solution i have calculated. The...

    Comsol-Pressure drop fluid flow in rectangular channel problem

    Thanks Minger, Actually your comment on the solver crash on seeing sudden high velocity at inlet was very useful. I remodelled as a time dependent file and now it works fine... Many thanks Arun

    Comsol-Pressure drop fluid flow in rectangular channel problem

    Dear all, I am trying to solve a simple model with Comsol to find the pressure drop in a rectangular channel W=5mm, h=0.6mm, L=10mm. When i try to set the inlet velocity to 0.5m/s the solver shows the error message "Maximum number of Newton iterations reached". The solver works fine if i set...
