The APM Solver solves for the potential flow around arbitrary bodies. The bodies are represented by structured or unstructured mesh in .stl format. The APM Preprocessor is first used to preprocess the mesh. During this step, the APM Preprocessor creates a .mdl file. The APM Solver uses the .mdl file to solve for the potential flow around the body. Please refer to the following sections for more information about the APM Solver:
For steady simulations the wake is assumed to be a flat surface extending to "infinity". Visit the steady simulations section for more information.
For unsteady simulations the wake is assumed "free", i.e. it is allowed to deform and interact with itself and the body. Visit the unsteady simulations section for more information.
The wake can be aligned with the average trailing edge bisector, the freestream velocity vector, or with a specific vector (predefined). Visit the wake section for more information.
The wake can interact with downstream body parts (e.g. horizontal and/or vertical tails) without causing numerical instabilities. Visit the interaction with the body section for more information.
The wake can be represented by viscous vortex particles. Visit the viscous vortex particle wake section for more information.
