I am using a "radio scanner" like application (OP25) to receive and decode digital to audio and then I am trying to re-broadcast the audio to my FM radio using...
Have you ever used secplus with a Raspberry Pi using [rpitx](https://github.com/F5OEO/rpitx) for transmitting? I saw that there is a "[encode_ook](https://github.com/argilo/secplus/blob/master/secplus.py#L178)" method for Security+ and I figure that could somehow be...
I modified the pyrit_cli.py file to add three new commands to separate handshakes into different capture files. strip_best_handshakes: Outputs the highest quality handshake for each AP to a single output...
This branch adds support for various cross sections named and parameterized based on MSC Nastran's beam library.
These changes allow the user to explicitly define the adjoint right-hand-side (rhs) for multiple quantities of interest. This brings the MAST implementation of adjoints closer to that implemented in libMesh....
This allows dirichlet boundary conditions, both zero and non-zero, to be applied on individual degrees of freedom. The formatting for defining BCs is similar to that of Nastran. The new...
This was implemented a long time ago but was never merged into master. This moves the definition of the PointLoad class definition from the examples into the library itself. This...
I'm been implementing some tests in MAST using Catch2. I've noticed in the [1D](https://github.com/MASTmultiphysics/mast-multiphysics/blob/master/src/property_cards/solid_1d_section_element_property_card.cpp#L1542) and [2D](https://github.com/MASTmultiphysics/mast-multiphysics/blob/master/src/property_cards/solid_2d_section_element_property_card.cpp#L1033) section property cards that the section stiffness properties require a MAST::ElementBase reference as an...
It appears that `compliance_output` does not consider point loads when it is being evaluated [here](https://github.com/MASTmultiphysics/mast-multiphysics/blob/master/src/elasticity/compliance_output.cpp#L86). I tested it on 2D representation of a cantilever beam, bending in-plane, both with 1...
Reviewing the stiffness matrix for Timoshenko beam's in Cook's finite element textbook (4th edition), when kappa-->inf (or k=1/kappa=0 in the Cook textbook), the bending stiffness matrix reduces to that of...
