Start to learn DualSphysics
edited March 2015
I knew Dualsphysics a few weeks ago and downloaded the guides and read them. Unfortunately I could not find how I can start modeling with that?
Are there any Tutorial to show that, step by step, modeling and solving a simple problem by DualSphysics?
Maybe you should start to build some simple models (for example a cube or a plate and a single spherical waterdrop) by using the DualSPHysics Preprocessing Interface. This helped me a lot in the beginning ! If you do not want to simulate the whole problem you can just use the Gencase tool to transform your geometry into a particle system and analyze what happened to your model in ParaView or something similar.
Reading the user guide and working with the testcases is a good way to understand DualSPHysics in my opinion.
I could load the examples in the per-processing interface.
What should I do after this stage?
It shows the geometry, boundaries and parameters. It means I have a case and now I want to solve it. How can i define the particles?
How to compile it?
How can I sea the results? I have para view but i do not know how to see the results?
You should study the batch or shell execution files of the examples with an editor.
In addition to that study the userguide. Everything is explained there !
I've recently start using DualSPHyics and I'm trying to set up a simple example to understand better how the software works. I have two different fluids (i.e.. water and oil) flowing in a pipeline. My question is: how can I define different densities/viscosities for each individual geometry?
This version is only ONE Phase. So sorry
Many thanks for the prompt reply.
Do you know if SPHysics would be adequate in dealing with more than one phase?
Also, is FreeCAD a good CAD tool for Linux OS? The DualSPHysics pre-processing interface is not suitable for more complex geometries (i.e. tubelines involving angles)
please check the new version v3.2 if you need to do two different phases, such as a Newtonian / Non Newtonian water/oil for example
When I started I made great advance by making little modifications to the case definition files of the examples.
