Re: WSS calculations directly from SimVascular

Hi Dave, Thanks for the answer and it would be great to extract wss from SV results. So there is a range of WSS values not just WSS on the surface. So which value of this range is reported if a vtp file is used? just the maximum on the surface? or the mean of the range within the element? Thank you,...

Re: WSS calculations directly from SimVascular

About the wss along a line, I still don't understand why more than one point on each end of the line should be reported. The image attached showed the velocity and wss along a segment of the line (all the pink dots are WSS values which increase dramatically along the line). I would expect to see one...

Re: WSS calculations directly from SimVascular

Hi Dave, I would like to check WSS results read in Paraview with a step- by step extracted one,as you explained, in a program (that could be what?). The reason is that I have seen regions of high WSS (compared to previously reported data for the coronary simulations) and try to make sure they are ac...

Re: WSS calculations directly from SimVascular

Hi Dave, Thanks for the info. I was wondering to know if it is possible and how I may use this code directly (probably in SV console) to extract WSS. Another question is when using Paraview, if a line is intersected with a radial cross-section, instead of having presumably two WSS values (two points...

Re: WSS calculations directly from SimVascular

Hi Dave! I looked at the code, however due to high number of variables, I did not figure out which variables were used to calculate WSS. As defined, WSS is the velocity derived tangential stress. I was interested to see if I can calculate WSS from the velocity as well as the normal to the cell and t...

WSS calculations directly from SimVascular

Hello,

I was wondering to know how I may extract (calculate) WSS values directly from SimVascular not Paraview.

Thank you and looking forward to your reply,
Ati

creating wall.ebc in the new version

Hello,

I was wondering if there is any way to extract "wall.ebc" file? (as used in the older versions)

Thank you,
Ati

Re: Simulations not running on a Window 10 system

Hi Amirtaha,

Actually I have the model smoothed out, but for one of my models specifically, meshing worked for a less smooth model :)
Thanks anyways,

Ati

Re: Simulations not running on a Window 10 system

Hi Amirtaha,

Thanks for your answer! Do you mean smoothing the model before the meshing?
I will try that.

Thanks,
Atefeh

Simulations not running on a Window 10 system

Hello, When I run the simulation on a local computer (using 36 out of 40 logical processors), simulation is finished after one minute (predicted to take about 3 to 4 hours running time) with no error or warning and the prcos-case file includes only a few files including bct.dat, rcrt.dat. I was wond...
