    SPH Fluid Damping — How to Set Artificial Viscosity and Bulk Coefficients for Water vs PDMS in Abaqus/Explicit?

    Thank you — yes, I’ve checked the documentation and I understand the purpose of artificial viscosity vs real viscosity. I also looked into the "Splashing of a Figurehead" example, but in the .inp file I found, the <AlphaFactor> and <BetaFactor> tags are there but not assigned any values. Also...

    SPH Fluid Damping — How to Set Artificial Viscosity and Bulk Coefficients for Water vs PDMS in Abaqus/Explicit?

    Hi everyone, I’m working on my master’s thesis and would really appreciate some help understanding how to properly define artificial viscosity and bulk damping for different fluids in Abaqus/Explicit SPH. Model setup: I am modeling a Wind Turbine (WT) system as a single-degree-of-freedom...

    Need Help Extracting SPH U1 Nodes with Python

    Hi everyone, I am trying to extract U1 displacement for SPH nodes in Abaqus using Python. My goal is to write the displacement values to a CSV file, with time in the first column and displacements for each node in the subsequent columns. Here is my script: # -*- coding: utf-8 -*-...

    How to Properly Implement Viscosity in SPH Using ABAQUS Explicit Analysis?

    Hello everyone, I have a question regarding the use of viscosity and artificial viscosity in Smoothed Particle Hydrodynamics (SPH) for ABAQUS Explicit dynamic analysis. Here's the setup I'm working with: I have a simple wind turbine modeled as a 2-point spring-dashpot system connected to a...
