Mean inflow value not matching

[Kelly Cao]

Hello,
The unsteady flow profile mean inflow value does not match the mean inflow value generated in the all_results-averages.txt. Is there a reason for this difference that I am seeing? If so, how would I fix this difference?

Any help would be appreciated!
Thank you,
Kelly

Does SimVascular have a limit on the number of point numbers?

Hi Kelly,

The values will not be exact but should match within a reasonable tolerance. How much are the values off?

Cheers,

Hello,
The values are off by 2600 (mm^3/sec).

Thank you,

Hi Kelly,

You are running you simulation in MGS units? When converting results are you selecting Sim Units to be mm?

Upload your SV project someplace I can download it and I'll have a look.

Cheers,
Dave

The SV project is uploaded onto the google drive: https://drive.google.com/drive/folders/ ... sp=sharing

Hi Kelly,

I looked at your project. The avg flow files look ok, off by a few percent probably due to interpolation and such.

Note that your simulations are not converging, need to experiment with mesh refinement, time step, Step Construction, and maybe Maximum Number of Iterations for svLS NS Solver, etc. You want the nonlinear residual to be around 1e-3.

Sounds good, thank you Dave! I appreciate your help.
