# stroid
|
|
||||||
A focused mesh generation suite, using an O-grid approach to generate high-quality stellar structure meshes for astrophysical simulations.
|
# Stroid
|
||||||
|
## A multi-block mesh generation tool for stellar modeling
|
||||||
|
|
||||||
|
Stroid is a simple multi-block mesh generation tool designed to generate multi-domain
|
||||||
|
meshes for 3D finite element modeling of stellar physics. It uses the MFEM library for
|
||||||
|
mesh generation and manipulation and is capable of generating high-order curvilinear
|
||||||
|
and non-singular meshes.
|
||||||
|
|
||||||
|
> Note: Stroid is under active development and is not yet stable. Features and interfaces may change in future releases.
|
||||||
|
|
||||||
|
## Building and Installing
|
||||||
|
Stroid uses meson as its build system, specifically we require version 1.3.0 or higher. Further,
|
||||||
|
stroid depends on C++23 standard library features, so both a compatible compiler and standard template
|
||||||
|
library are required. All other dependencies are handled by meson and will be downloaded and built
|
||||||
|
automatically.
|
||||||
|
|
||||||
|
### Building
|
||||||
|
```bash
|
||||||
|
git clone https://github.com/4D-STAR/stroid.git
|
||||||
|
cd stroid
|
||||||
|
meson setup build
|
||||||
|
meson compile -C build
|
||||||
|
meson test -C build
|
||||||
|
meson install -C build
|
||||||
|
```
|
||||||
|
|
||||||
|
### Running
|
||||||
|
Stroid can be used either from the command line or from C++. The command line interface is
|
||||||
|
the simplest way to get started. After installation, the `stroid generate` command should be available in your terminal.
|
||||||
|
|
||||||
|
```bash
|
||||||
|
stroid generate --help
|
||||||
|
```
|
||||||
|
|
||||||
|
The main way to interface with this is through the subcommands (currently only `generate` and `info` are available):
|
||||||
|
|
||||||
|
```bash
|
||||||
|
stroid generate -c <path/to/config/file.toml>
|
||||||
|
```
|
||||||
|
|
||||||
|
```bash
|
||||||
|
stroid info -d
|
||||||
|
```
|
||||||
|
|
||||||
|
to save the default configuration to a file named ``default.toml``
|
||||||
|
|
||||||
|
### Configuration File
|
||||||
|
Stroid uses a TOML configuration file to specify the parameters for mesh generation. An example configuration
|
||||||
|
file is found below
|
||||||
|
|
||||||
|
```toml
|
||||||
|
[main]
|
||||||
|
core_steepness = 1.0
|
||||||
|
flattening = 0.0
|
||||||
|
include_external_domain = false
|
||||||
|
order = 3
|
||||||
|
r_core = 1.5
|
||||||
|
r_infinity = 6.0
|
||||||
|
r_instability = 1e-14
|
||||||
|
r_star = 5.0
|
||||||
|
refinement_levels = 4
|
||||||
|
```
|
||||||
|
|
||||||
|
<!-- Table of what these parameters do -->
|
||||||
|
| Parameter | Description | Default |
|
||||||
|
|-------------------------|-----------------------------------------------------------------------------------------------------|---------|
|
||||||
|
| refinement_levels | Number of uniform refinement levels to apply to the mesh after generation | 4 |
|
||||||
|
| order | The polynomial order of the finite elements in the mesh | 3 |
|
||||||
|
| include_external_domain | Whether to include an external domain extending to r_infinity | false |
|
||||||
|
| r_core | The radius of the core region of the star | 1.5 |
|
||||||
|
| r_star | The radius of the star | 5.0 |
|
||||||
|
| flattening | The flattening factor of the star (0 for spherical, >0 for oblate) | 0 |
|
||||||
|
| r_infinity | The outer radius of the external domain (if included) | 6.0 |
|
||||||
|
| r_instability | The radius at which no transformations are applied to the initial topology (to avoid singularities) | 1e-14 |
|
||||||
|
| core_steepness | The steepness of the transition between the core and envelope regions of the star | 1.0 |
|
||||||
|
|
||||||
|
|
||||||
|
If no configuration file is provided, stroid will use the default parameters listed above. Further, configuration files
|
||||||
|
need only include parameters that differ from the defaults, any parameters not specified will use the default values.
|
||||||
|
|
||||||
|
### C++ Interface
|
||||||
|
Stroid can be used as a library in C++ projects. After installation, include the stroid header and link against the stroid library.
|
||||||
|
|
||||||
|
A basic example of using stroid in C++ is shown below (note that you will need a glvis instance running on localhost:19916 to visualize the mesh):
|
||||||
|
```c++
|
||||||
|
#include <memory>
|
||||||
|
#include "mfem.hpp"
|
||||||
|
|
||||||
|
#include "stroid/config/config.h"
|
||||||
|
#include "stroid/IO/mesh.h"
|
||||||
|
#include "stroid/topology/curvilinear.h"
|
||||||
|
#include "stroid/topology/topology.h"
|
||||||
|
|
||||||
|
#include "fourdst/config/config.h"
|
||||||
|
|
||||||
|
int main() {
|
||||||
|
const fourdst::config::Config<stroid::config::MeshConfig> cfg;
|
||||||
|
|
||||||
|
const std::unique_ptr<mfem::Mesh> mesh = stroid::topology::BuildSkeleton(cfg);
|
||||||
|
stroid::topology::Finalize(*mesh, cfg);
|
||||||
|
stroid::topology::PromoteToHighOrder(*mesh, cfg);
|
||||||
|
stroid::topology::ProjectMesh(*mesh, cfg);
|
||||||
|
|
||||||
|
|
||||||
|
stroid::IO::ViewMesh(*mesh, "Spheroidal Mesh", stroid::IO::VISUALIZATION_MODE::BOUNDARY_ELEMENT_ID);
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Example Meshes
|
||||||
|
An example mesh with the default configuration parameters is shown below (coloration indicates attribute IDs of different regions):
|
||||||
|
|
||||||
|
|
||||||
|
