How do we scale the 'non-linear residual'?

Hi everyone, From one of the other discussion posts, I saw that Simvascular uses the generalized-alpha method and the 'non-linear residual' as defined in equation (24) and (10) of [1]. Firstly, is this is the way Simvascular defines residual? Qualitatively, I understand that the accuracy of the simu...

Residual criteria (relative or absolute norm)

Hello, Does anyone know the mathematical form of the residual norm we try to bound by the following lines of code in solver.inp "Residual Control: True Residual Criteria: 0.01" 1. In particular, what does the parameter 'residual criteria' imply ? Would this monitor error norms on velocities or press...

Re: Velocity data throughout the mesh

Hi Adam,

Thanks a lot for explaining! Yes, I am using Paraview for post-processing. Thanks for pointing out, "Filters-->Data Analysis-->Calculator" indeed gives me what I wanted.

Thanks,

Velocity data throughout the mesh

Hello, I am post-processing the cylinder case from the sample dataset. I am particularly interested in velocity vectors throughout the volume, however the vtu and vtp files seem to indicate only velocity magnitude throughout the mesh. Is there anyway to get velocity data throughout the domain ? I wo...
