Kevin Moerman 🔓🦿:julia:Just read about "rabbit functions", a term for math expressions that are essentially "pulled out of a hat"! Love it, and have to use this in a paper some day. From "Wachspress 1975, A Rational Finite Element Basis: "A "rabbit function" is a function that is pulled out of a hat. When a magician pulls a rabbit out of a hat, the effect astonishes the onlookers. Once the illusion is revealed, the rabbit generation is no more surprising than the generation of rabbits by rabbits."<a href="https://fosstodon.org/tags/FiniteElement" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FiniteElement</a>

AndreasFor my <a href="https://mathstodon.xyz/tags/fortran" class="mention hashtag" rel="tag">#fortran</a> tensor toolbox (module) I'd like to add some unit tests. Unfortunately, my knowledge and experience in Fortran ends with writing this little toolbox and some user materials for <a href="https://mathstodon.xyz/tags/fea" class="mention hashtag" rel="tag">#fea</a> software like <a href="https://mathstodon.xyz/tags/abaqus" class="mention hashtag" rel="tag">#abaqus</a> or <a href="https://mathstodon.xyz/tags/marc" class="mention hashtag" rel="tag">#marc</a>. Do you have any recommendation or tutorials on how to add unit tests to a <a href="https://mathstodon.xyz/tags/fortran" class="mention hashtag" rel="tag">#fortran</a> module? Ideally with Github Actions integration... 💡 Thanks!<a href="https://mathstodon.xyz/tags/fea" class="mention hashtag" rel="tag">#fea</a> <a href="https://mathstodon.xyz/tags/scientificcomputing" class="mention hashtag" rel="tag">#scientificcomputing</a> <a href="https://mathstodon.xyz/tags/fortran" class="mention hashtag" rel="tag">#fortran</a> <a href="https://mathstodon.xyz/tags/finiteelement" class="mention hashtag" rel="tag">#finiteelement</a> <a href="https://mathstodon.xyz/tags/unittests" class="mention hashtag" rel="tag">#unittests</a> <a href="https://github.com/adtzlr/ttb" target="_blank" rel="nofollow noopener noreferrer" translate="no">https://github.com/adtzlr/ttb</a>

TuxRiders📢LAST VIDEO OF THE YEAR 😇Choosing a proper solver can be quite important for <a href="https://fosstodon.org/tags/FiniteElement" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FiniteElement</a> models. In this video, we discuss a bit about various available solvers in <a href="https://fosstodon.org/tags/FreeFEM" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FreeFEM</a>, including <a href="https://fosstodon.org/tags/PETSc" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PETSc</a> with which we have access to tremendous number of tools, solvers, and preconditioners to solve the derived linear system of equations more efficiently. <a href="https://youtube.com/watch?v=wGYez2-3rvk&ab_channel=TuxRiders" rel="nofollow noopener noreferrer" target="_blank">https://youtube.com/watch?v=wGYez2-3rvk&ab_channel=TuxRiders</a><a href="https://fosstodon.org/tags/Modeling" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Modeling</a> <a href="https://fosstodon.org/tags/Simulation" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Simulation</a> <a href="https://fosstodon.org/tags/FEA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FEA</a> <a href="https://fosstodon.org/tags/OpenSource" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#OpenSource</a>

Kevin Moerman 🔓🦿:julia:A ridiculous <a href="https://fosstodon.org/tags/FiniteElement" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FiniteElement</a> model for whoever wants to simulate a rubbery propeller hitting a stick.

TuxRiders⚡NEW VIDEO⚡One of the features in <a href="https://fosstodon.org/tags/FreeFEM" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FreeFEM</a> offering flexibility for <a href="https://fosstodon.org/tags/FiniteElement" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FiniteElement</a> models is the regions and sub-domains, which can be used to define different properties in different parts of the mesh, like a multi-material model. <a href="https://youtube.com/watch?v=g43w0iZFE-c&ab_channel=TuxRiders" rel="nofollow noopener noreferrer" target="_blank">https://youtube.com/watch?v=g43w0iZFE-c&ab_channel=TuxRiders</a><a href="https://fosstodon.org/tags/FEA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FEA</a> <a href="https://fosstodon.org/tags/FEM" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FEM</a> <a href="https://fosstodon.org/tags/engineering" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#engineering</a> <a href="https://fosstodon.org/tags/EngineeringMath" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#EngineeringMath</a> <a href="https://fosstodon.org/tags/opensource" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#opensource</a>
