Compiling Simvascular on EXPANSE (SDSC HPC)
Hello, We recently compiled svSolver on EXPANSE (SDSC HPC) and successfully ran jobs on it. We are trying to compile Simvascular as well from the source code in the following link: https://github.com/SimVascular/SimVascular All necessary modules that we used to compile svSolver were loaded for Simva...

segmntation error: SplinePolygonSegmentation.set_control_points()
Hello, We are defining a spline polygon using python api based on a set of points created from intersecting a plane with a stl. However, we receive an error when assigning control points. Here's the error: segmntation error: SplinePolygonSegmentation.set_control_points() The 'points' data do not lie...

Re: Replicating mesh generated using Python script with the one in SV gui
Hi Dave, Sorry for the late reply. Yes, we used radios-based meshing that correctly mesh the stenosis. We actually want to get rid of large elements near aortic. I think the only parameter to control element size is global max edge size. When we have stenosis, this value should be smaller to get a r...

Re: Replicating mesh generated using Python script with the one in SV gui
Hi Dave, Just a follow-up question. I used the same mesh setup for the models shown below using a global max edge size of 0.015. RCA (left one) looks okay with a reasonable surface element size. But for LCA (the right one), large elements are visible. I think that's due the the stenosis as I marked ...

Re: Replicating mesh generated using Python script with the one in SV gui
Hi Dave, The issue was with radius_meshing_scale. The default value for this is 0.1. To fix this issue, we used our assigned edge size for radius_meshing_scale and got the same mesh that sv GUI generates. Here's the updated options in the code: print("\nSet meshing options ... ") options = sv.meshin...

Re: Replicating mesh generated using Python script with the one in SV gui
Hi Dave, Thanks for your help. We actually got it. options.radius_meshing_centerlines = centerlines didn't work, though. But we added two lines that worked and got the mesh similar to sv gui. options.mmg = False options.radius_meshing_compute_centerlines = True The only issue is that changing the va...

Replicating mesh generated using Python script with the one in SV gui
Hello, We generated a mesh in SV gui as shown below that has a pretty nice element size around the stenosis. fig1.JPG Parameters assigned for this mesh are: fig2.JPG We tend to do the same using Python code. Our current code, attached here, generated the mesh that is not desirable. fig3.JPG What cha...

Stop simulation based on residual using python/batch script
Hello,
The simulation stops in Simvascular using a specified number of timesteps. I'm doing steady simulations and want to stop the simulation based on a specified residual, i.e. stop calculation at residual less than 1e-6. How can we do this using Python or batch script?
Thanks,
Jimmy
