Question #658938 on Yade changed: https://answers.launchpad.net/yade/+question/658938 kawsarahmed posted a new comment: Modeling the presence of water can be approached in various ways depending on the context and the specific requirements of the problem. Here are a few common approaches: Physical-based models: These models simulate the physical processes related to the presence of water. They take into account factors such as precipitation, evaporation, runoff, and infiltration. These models typically use equations derived from fundamental principles of physics and require input data such as topography, climate data, and land cover information. Examples of physical-based models include hydrological models like the Soil and Water Assessment Tool (SWAT) or the Hydrologic Engineering Center's Hydrologic Modeling System (HEC-HMS). Statistical models: Statistical models use historical data to identify patterns and relationships between different variables associated with the presence of water. They can be used to estimate the probability of water occurrence based on various factors. For example, you could use logistic regression or decision tree algorithms to predict the likelihood of water presence based on variables like rainfall, temperature, soil type, and vegetation cover. These models require a significant amount of data for training and validation. Remote sensing and GIS-based models: Remote sensing data, such as satellite imagery, can be used to detect and monitor water bodies. By analyzing the spectral characteristics of the imagery, you can identify areas with water presence. Geographic Information System (GIS) tools can then be used to process and analyze this data, overlaying it with other relevant geospatial information. This approach is particularly useful for monitoring changes in water bodies over time. Machine learning models: Machine learning techniques, such as neural networks, can be used to model the presence of water. These models can be trained on labeled datasets that contain information about the presence or absence of water in specific locations. By analyzing various input features, such as satellite imagery, climate data, or topographic information, the model learns to identify patterns and make predictions about the presence of water in new locations. It's important to note that the accuracy and effectiveness of these models depend on the quality and availability of input data, as well as the complexity of the problem being addressed. The choice of modeling approach should be based on the specific requirements and available resources for the task at hand.

I would recommend to have it written along with the explanation of StressMask in the section for Triaxial stress controller. That would be the best spot for people to understand the usage clearly. I actually had a question in mind but forgot it mid-way. Will write as soon as I remember. 3) In a standard 1D oedometer test, the top plate is loaded and the sample is drained/undrained (from top/bottom). a) I can see the spheres growing in size. I am not sure if they are doing so with the expulsion of water from the pores ( because I cannot visualize the fluid phase in the simulation. I guess Yade does not include that yet). Going by the concept of soil mechanics, should the volume of the solid particles not remain constant? Why do the spheres have to change their volume. It should only be the total volume of the sample that would change with the consolidation occuring. Am I getting something wrong :) ? b) Could you please try running the script.

I have the following questions now:
1) StressMask : I am still trying to get acquainted with the concept applied
there. But I found this useful note in one of the scripts:
### switch stress/strain control using a bitmask. What is a bitmask, huh?!
## Say x=1 if stess is controlled on x, else x=0. Same for for y and z,
which are 1 or 0.
## Then an integer uniquely defining the combination of all these tests
is: mask = x*1 + y*2 + z*4
## to put it differently, the mask is the integer whose binary
representation is xyz, i.e.
## "100" (1) means "x", "110" (3) means "x and y", "111" (7) means "x and y and
z", etc.
This helped me get a better idea ;)
2)
a) For a 1D (z axis flow) we would need: triax.goal1=triax.goal2=0
triax.goal3= -1 .
Is it correct?
b) For flow drained at the top and bottom undrained it should be:
flow.bndCondIsPressure=[0,0,0,0,0,1]
flow.bndCondValue=[0,0,0,0,0,0]
I think this is how the bit stream works here?
3) Plot:
Is the addPlot data section to measure the change in thickness fine? I am
not sure where I am going wrong. All I see is the Dz value constantly 0
with time.

Question #658938 on Yade changed: https://answers.launchpad.net/yade/+question/658938 Bruno Chareyre proposed the following answer: 2) The short answer is "keep it =3". If =0 you will use a less efficient strategy for solving. Other numbers will not work. Misleading, I agree. 3) The 6 values are for the six boundaries, sorted as in x-,x+,y-,y+,z-,z+. I think the example script oedometer.py illustrates that very well, and it answers directly your sub-question on "1D consolidation along Z .axis". 4) see 2) 5-1) ---> "Is it not important to provide the density of the fluid we are using. for example water .." No it is not. A viscous flow (assumption of this coupling) depends on viscosity only. You need to keep in mind that "pressure" in the model corresponds to excess pore pressure, i.e. something in addition to the hydrostatic pressure. The latter depends on density as you suggest but it causes no flow, it is not reflected in FlowEngines's pressure.. 5-2) Please check the example script again.
