[farah deba]

Hello adam

i wanted to simulate the aortofemoral artery model.
As its a hollow model so for face extraction i first applied triangular filter in paraview and saved it as .stl format
then i apply face extraction operation in SV modelling module and when i delete each cap setting sep.angle as 15 the error in below image pop up .
kindly guide me how to solve this issue.

Hi Farah,

I'm a little confused. You say you delete each cap and then try to extract faces? To delete the caps, you will have faces to begin with then? If you could clarify what you are trying to do, that would be helpful.

Where did you get this model?

Thanks!

hi adam,

the model is downloaded from an open source repository and it was in CAD format.
to use in SV for meshing and simulation i apply the triangle filter and convert the file into .stl
and to extract the hidden model faces i kept sep. angle option as 15 extract faces and delete each cap then to make one wall model when i extract the faces again with angle as 90 this error appear and crash the system.
i don't know how to solve it,please guide me.

Hi Farah,

So you extract faces, delete caps, and extract faces again?

I've just tested this out with a simple model, and it worked fine, so it may be specific to your model.

If you share your project, I can take a look when I have the chance.

Thanks!
