Re: [Yade-users] [Question #703836]: How desiredPorosity works?
Question #703836 on Yade changed: https://answers.launchpad.net/yade/+question/703836 Status: Open => Answered Robert Caulk proposed the following answer: Hello, By default, `FlowEngine` computes the volume of water in a cell to be equivalent to the full tetrahedron less the sphere fractions. `desiredPorosity` allows the user to reduce the total volume of water in the specimen by multiplying the default cell volumes by a volumeCorrection factor: volumeCorrection = desiredPorosity/actualPorosity cell_volume = volume * volumeCorrection This has an effect on compressible fluid simulations and heat diffusion. It does not change the structural sphere packing.

[Yade-users] [Question #703839]: appendClumped
New question #703839 on Yade:
https://answers.launchpad.net/yade/+question/703839
I was trying to run a code for which i already have an inputfile generated fro
another code in the x_y_z_r_clumpid format.
For the following part of my code i am getting error. What is the correct
format to use appendClumped and ymport.textClumps? What discretization means??
In yade document it tells ymport.textsClumps have default x_y_z_r format..how
to change that??
# - Adding Spheres to the Simulation
-
inputfile = 'Clumped.txt'
spheres=O.bodies.appendClumped(ymport.textClumps(inputfile),material=material,discretization=0)

[Yade-users] [Question #703836]: How desiredPorosity works?
New question #703836 on Yade: https://answers.launchpad.net/yade/+question/703836 Hello, So how dose desiredPorosity in the flow engine work? The description only says "Correct the cell volumes to reflect this desired porosity". Does that means even if I pack the particles loosely, I can just change the desiredPorosity into a low value and get a tight rock? It would be great if there is some sort of paper you can direct me to look up. Thanks.
