2021年2月17日 · Here is what I think is an improved version. At least the result looks more reasonable. The major changes are as follows.

2020年3月16日 · I solved the problem above using FiPy library for Python, see the code below. from fipy import * from fipy.tools import numerix from fipy.variables.faceGradVariable import _FaceGradVariable viscosity = 5.55555555556e-06 pfi = 10000. #Penalization for …

Is it possible to increase performance with FiPy? I feel like the nx, ny, nz bins are very small here, despite a long computation time. I don't understand why the arrays X, Y, and Z are so large. Notice in the first frame, we are zoomed in. How can I force the extents to automatically be [0..nx, 0..ny, 0..nz] in all plots?

2019年5月10日 · After running this, the FiPy solution seems to be quite close to the analytical result. The two important changes from the OP's implementation. Using mesh.x which is the correct way to refer to the spatial variable for use in FiPy equations. Specifying the solver and number of iterations.

2013年8月2日 · I would like to install Fipy on Python3.3 (Windows 7 or Linux/ubuntu-mint), is possible? I need to use Fipy for improving my python3.3 coding. Do I have to translate that in python 2.7 ? Please does

2014年9月25日 · FiPy needs one of PySparse, Scipy or Trilinos as a linear solver and Scipy is probably the easiest to install. To check that FiPy has access to a linear solver, you can run the tests, $ python -c "import fipy; fipy.test()" It should be evident from the test output if FiPy does not have a solver library available.

2016年9月18日 · The default fipy condition is the former (value = 0), but the explicit method (faceGrad.constrain) is the latter. The issue can be understood by adding the following code to the end of the fipy diffusion.mesh20x20 example and noting different face gradient results.

2021年2月9日 · I am trying to solve the following problem using fipy but I am a bit overwhelmed. Hoping someone can point me in the right direction. C and q are the dependent variables and I am solving in 2 dimensions, time (t) and length (z).

2024年3月8日 · For time integration, FiPy performs forward-Euler steps, although our first example illustrates how to obtain backward-Euler and Crank-Nicolson integrations. I have an associated package in development called Steppyngstounes that offers some other time integration schemes that can be used with FiPy.

2023年9月27日 · Thank you for your feedback 🙏. I tried the equation you suggested, and while the pressure profile improved, it still doesn't match my two analytical benchmarks. The expected pressure should decrease, then stabilize at a certain depth. However, the FiPY solution seems influenced by the column height (Lz).
