A Taylor-Hood finite-element pair is a suitable choice for the Stokes equations. However, using Quadrature elements generates some bugs in this representation and we therefore need to revert to the old representation. FEniCS was a good choice as the base of our implementation, allowing us to focus on the models and numerical methods rather than on implementing stan- dard algorithms.

MSO4SC-FEniCS unlocks scientific reproducibility for HPC. For the thermomechanical model, in the absence of inertia effects, the mechanical part of the solution is governed by: (4) − ∇ ⋅ σ = f in Ω, (5) σ ⋅ n = p bc n on Γ N u, (6) u = u bc on Γ D u, where σ is the stress tensor, f is a prescribed body force, p bc is a prescribed boundary pressure, u is the displacement field and u bc is.

In practice, there are two (easily fixable!) issues with the above approach; firstly, on each call to docker run we get a completely fresh container, meaning that the Instant cache of compiled objects needs to be regenerated everytime, and secondly the above command is rather cumbersome to type out. The problem is still there if one replaces P2×P1 by P1×P1. to LogLevel.

Later, these changes were used to represent complex values in XDMF. write() for I/O. Detected hard-coded path in text file bin / saws / SAWs. I have not got decent code to show now, sorry. Suppose that `u` is such a `Function`, its Numpy array is well defined (1-d array) and gives correct values. I am using the Java HDF5 library from HDFView to. The control function is the Dirichlet boundary value on the velocity field and is hence be a function on the velocity space (note: FEniCS cannot restrict functions to boundaries, hence the control is defined over the entire domain). This demo is implemented in a single Python file, demo_elastodynamics. The Open Source code and computation are made easily reproducible, modifiable and inspectable by the Open Source MSO4SC cloud framework, here with a web interface of a familiar desktop environment.

This demo program solves the nonlinear Naghdi shell equations for a semi-cylindrical shell loaded by a point force. In this section we cover some common workflows that you might find useful. Now I need to import that into ANSYS for further analysis.
