Re: Problem simulating simple geometries (negative pressures)

I am facing same problem but my model is right coronary artery and flow is pulsatile.

Basic Information

Hi,
I just want to know do simvascular consider gravity/or not while simulating.

Re: negative pressure significance

sorry for bad quality image, i am sending with better view. yes,my inlet velocity is negative and i have also shared models and inlet data via google drive previously again previous query remain same I have run a simulation of pulsate nature for 3 cycle but the result comes is negative at inlet pres...

negative pressure significance

Hi, I have run a simulation of pulsate nature for 3 cycle but the result comes is negative at inlet pressure and approximate zero at outlet pressure flow should be in high pressure to low pressure(by voltage analogy) but mine is coming negative; is it mean vacuum pressure(not on absolute scale)? tha...

Re: Basic parameter in simulation section

when we export the simulation result in paraview,the naming which we give in simvascular(inlet_cap and outlet_cap) is not exported ,so it is difficult to know which one is inlet and which one is outlet. SECOND QUESTION what is output dimension of simulation result when previewed in paraview in legen...

Basic parameter in simulation section

Hello, I just wanted to know what are function of 1)Initial pressure 2)initial velocity in Basic parameter in simulation section.We already feed volumetric flow rate in boundary condition. SECOND QUESTION In case of cylinder example tutorial problem ,when we export our simulation results in paraview...

Simulation issue

I am trying to perform flow simulations with the aorto-femoral models supplied in the SV model repository. However I always encounter errors or crashes when I click "Create Data Files for Simulation". The error I receive is "Failed to finish creating data files" with no details provided. In the bott...

meshing issue

In case of a very small distance between two artery, there shows a meshing error
