TAWSS and OSI results are zero #6

Open ktbolt opened 5 months ago

ktbolt commented 5 months ago

Description

It seems that all VMR datasets have TAWSS and OSI results that have all zero values.

Reproduction

I check simulation results for

  1. 0024_H_AO_H
  2. 0004_H_AO_SVD
  3. 0014_H_AO_COA
  4. 0013_H_AO_COA

All of the results for these datasets had zero TAWSS and OSI results.

Expected behavior

I would expect the datasets to have non-zero TAWSS and OSI results.

Additional context

@natalia-rubio I have a script that adds WSS to simulation files. I was planning on using it on every simulation on the VMR but I never found the time to check that the WSS computed with the script actually matches the output of SimVascular. If you have some simulations with embedded WSS, you could try see how close the WSS are and if they match just apply it to all simulation files on tetra (I would back the data up first).

(Copied vascularmodel to Skalak.) Thanks Luca, I could check your script on one of my junction simulations, those include "vWSS". Where would I find the script? Is the idea that once we have WSS we compute TAWSS and OSI by averaging over the last cardiac cycle?

@natalia-rubio I sent you the script via email. The script only computes WSS. I am not sure what the best way to compute TAWSS and OSI is. There might be some experimenting with the Pawaview module to do, bu we can brainstorm together.
