about the definition about the WSS spatial gradient

Hello, the developers. During the postprocessing in paraview, we can directly get the WSS ,average WSS, OSI. now i want to get the WSS spatial gradient, definition.png .the question is when i define it in the 3D simulation, which direction i should follow? how to define it,thanks so much for your he...

Re: failed meshing

Thanks so much for your reply! I tried to change the caps to the wall, and it worked. And there is also another question please, i scaled up the stent part(the figure is attached), it seemed that the mesh changed the shape of geometry, I am wondering that how i can solve this problem? Thanks so much...

failed meshing

hello,
I want to make a new cylinder model aiming to simulate the existance of stent simply, but it failed meshing. It shows that there are two many regions,I really don't know how to do with it.
I also attached the model i created, maybe it will be more clear to find the problems.
Thanks so much.

about the average speed in paraview

Dear Simvascular developers, I have a little question please. when we see the visualization in Paraview, there are options for us to see the average speed distribution and average pressure distribution, i am a little confused, what's the relationship with velocity and pressure, and what do they mean...

about non-newtonian model

Dear Simvascular developers, 1. Is there a way to input non-newtonian flow model inside Simvascular. it seems that i can just input a constant for the viscosity term. 2. In simvascular if it can has a library for the artery models and stent models inside. If i want to inert a stent model into the ar...

Re: if the calculation of velocity magnitude is necessary

Thanks so much for your reply. And i see that as you said, before the calculation with the magnitude option it shows the velocity vector with three direction components. after the calculation mag(velocity), it shows the value calculated as: sqrt(x_component^2 + y_component^2 + z_component^2). and th...

if the calculation of velocity magnitude is necessary

Hello everyone, I have a question about the calculation of the velocity magnitude. i see when we show the velocity distribution in the example, we need make a calculation mag(velocity) to get the unit of cm/s. i want to know if the calculation is necessary, if we don't do it, what's the unit. and it...

the outlet flowrate of the rigid and deformable ones

Hello everyone, For the cylinder model, i compared the outlet flowrate between the rigid and deformable one, but there is a big difference between them, so i want to know if it is normal, for the defomable one i got it based on the final step result of the rigid one, and pick the fifth cycle when th...

Re: the possibility for import a stent model inside a vessel in Simvascular

Hi,thanks so much for your quick reply.
There screenshot of the pressure distribution is attached when the pressure is maximum.and the mesh element is about 70000.

Re: the possibility for import a stent model inside a vessel in Simvascular

Thanks so much for your reply. And i tried with the RCR BC.now i fix the value of RCR(for the both oulets):600 0.00015 6000. i can get the pressure range:inlet:78-153mmHg, outlet1:79-105mmHg, outlet2:80-112mmHg.we can see the outlet pressures are in the normal range,but the range of inlet pressure i...
