Hello everyone,
I have just finished running a simulation of an aorta and have some doubts about the units in post processing: i should have been consistent with CGS system, ie:
- Model in cm
- Flow rate in cm^3/s
- Rp and Rd in g/(cm^4*s)
When i convert results and select 'Sim units cm', are the velocity values calculated in cm/s?
The doubt comes because i think i have set the parameters correctly but when studying in Paraview, i get rather low values.
Finally, still using the same units, what would be the units of the calculated pressure?

Best regards,
Gianmarco.

Hi Gianmarco,

The svSolver does not assume any units. The units of your mesh, boundary condition data and physical constants just need to be consistent.

The Sim units cm option is used to write flow data to a text file, it does not affect the simulation results stored in VTK files.

Pressure would be in dyne/cm^2 for CGS units.

Does the simulation converge to a steady state ?

Cheers,
Dave
