Can I increase number of cells more than 1000 in the plane ?

Can I increase number of cells more than 1000 in the plane ?

Hi Abdallah,

I believe it shows error if you try to increase cells apart from (0 - 1000)... In Flow, advanced Mesh Technique Adaptive (global scale 6 - 8) itself will use far less than 1000 cells in each of X, Y & Z..... And I practically don't see any necessity to use such huge cells unless you are using super computers to solve the problem else would run for ages to solve in workstations... !!!

Use Initial mesh....

**Well my model isn't big at all i am simulating a couette flow and the thickness of the fluid is so small that when I use automatic mesh of 8 the cells are too big for this small thickness and I get wrong solution I tried to use manual but I see I can control only the number of cells so I use maximum number of 1000 the solution near the exact solution now but there still an enough error to increase number of cells again or if you can help me controlling the size of theses boxes in mesh I will be very thankful cuz I tried all I can.****is there any way to increase number of theses cells ( i need as much as possible between these two parallel plates shown in picture) rather than increasing number of cells in the plane ? (note this is taken picture when i used 1000 cells inside the plane)**)Well I solved this problem using same assumption:

with Navir Stocks equation and I got the exact solution if we compare between the exact solution and solidworks solution

Vmax=1.15 m/s (exact)

Vmax=1.039 m/s (Solidworks)

Vav=0.446 m/s (exact)

Vav=0.39m/s (solidworks)

The separation point is 7.9 mm away from the lower plate in exact solution and is 7.7mm in solidworks solution.

Am I consider myself reached right solution I see there is still an enough error to make theses cells more.

There is no way to make them let's say 25 cells across this channel ?

before you go crazy with mesh

i'd suggest you make a much smaller/simpler version of your problem and see if the problem is actually that sensitive to mesh

you've got like a 10% "error" here

or go with a much coarser mesh

**well thank you Jared i looked again for my assumption i found that i didn't include Fully developed flow in my assumptions in solidworks because i can only add them in inlet velocity or outlet velocity conditions and in my case it's pressure inlet and outlet conditions my exact solution is based on fully developed flow that's why the numbers are different now the numbers seems to be right.**

you have almost 10 cells across that channel, why do you need more?
