Hi all
I have 6 mm artery witn aneurysm and I want to do mesh independency test. I chose 0.4 mm mesh size for artery and 0.2 mm for aneurysm with scale factor 1 and 3 layers prism mesh which gives me around 400000 elements. I 'm not really sure how should I change the mesh size for independency test. I tried 1000 times changing parameters and check the total pressure difference at inlet and outlet. but still can not get a smooth line for this test. My convergence with residual 10-5 is good and I have no idea what's wrong. I even try until 1000000 element but every time the answer is different. Any suggestion would be appreciated.


Thanks
