Re: SimVascular experience? Can't run simulation.

Does anyone have any experience doing flow simulations in SimVascular? I've been looking at the user guide and I've successfully made it past the meshing step, but when it comes to actually running the simulation, I've been coming pu against errors time and time again. Some of the files I need aren...

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

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? http://simvascular.github.io/ https://domyhomeworkonline.net/ https:/...

Re: non-acurate pelvis velocities in local frame. Is this due to Gimbal lock?

Hi everyone. I am trying to solve a problem where I need to calculate Angular velocities in local frames. I just realized that pelvis's orientation can affect it's local angular velocities. Please take a look at thesimplified MATLAB script. In this case my model has 1 body only (pelvis) which has 6...

Re: Scaling tool fails at "placing markers on model"

Hello I'm a new user of opensim, so maybe the answer to my question could be very easy to you. I have some Vicon PlugInGate data, which I converted using the LeeSon Tool box. When I now display the experimental Data it looks fine. I use the PlugInGait model from Tim Dorn, added his marker model aft...
