Most computational fluid dynamics (CFD) algorithms use Eulerian methods, in which flow moves through fixed, regular triangular or rectangular elements.

Here is the first of several new high-order methods for vorticity-based CFD that my collaborators and I have created.Ī. Often, though, the algorithms are more intricate and possibly less stable. Thus, fewer computational elements or time steps are required to achieve the desired accuracy. "High" order methods approach the true solution (their expected error scales) with the 3rd or higher power of the element or time step size, so using elements half as large makes the error one eighth as large or better. First order methods, for example, have an error term that changes linearly with the element or time step size: elements are half as large means the error is half as large. The "order" of a computational method is the power of the error term on the element size or time step size.

And in 2021 we were the first to hybridize a high-order Eulerian method with our open-source Lagrangian Vortex Particle Methods solver, resulting in much smaller overlap regions than any previously reported work.

At ASR, we pioneered this combination in 2010 with a system joining NASA's OVERFLOW2 code with our OmegaFlow GPU-accelerated 3D vortex particle method. Hybrid CFD methods aim to leverage the benefits of both types of solvers, using Eulerian methods near boundaries or in regions of high gradients, and Lagrangian methods in unsteady convecting wakes. See my research on ORCID Hybrid Lagrangian-Eulerian Methods In addition, I am interested in GPU and parallel programming, computational geometry, cellular automata, and high-resolution image rendering and display. In the last two decades I have created a number of Eulerian, Lagrangian, and hybrid vortex methods in both two- and three-dimensions, some independent and many with Applied Scientific Research in Irvine, California, USA. My research focus is vortex particle methods for flow simulation. I hope its future will be secured.Mark Stock - Research Mark Stock Research Basically, it's the only one portfolio tracking & techanalysis alive FOSS program I could find. I really like the program and it's quite sad to find its source in this unusable state.

Better to resolve the issue (rewrite questionable parts and such) and make it free again. If you've already violated someone's rights it's no use hiding the source. To avoid involving myself into some legal issues, I decide make it as a closed source component.

The legal license text only translates these ideas to the legal language but of course, if unsure consult a lawyer.

Overall, you don't have to be a lawyer to check if you software is in agreement with GPL, just read the aforementioned article and answer to yourself whether your product complies with the four freedoms or not from the user's standpoint. Quoted from gnu.org, accentuation is mine.
Access to the source code is a precondition for this.
The freedom to study how the program works, and change it so it does your computing as you wish. Now it seems that the essential part of the program, the core, is unavailable and violates the user's freedom number 1: That said, the repository doesn't include a license file but the source files have the license in their headers. The GPL license is viral so everything that includes GPL code and is being distributed in binary form should be open to study and modifications by means of providing the source code. Yes, this program is in violation of GPL terms.
