t8_time_prism_adapt.cxx
The t8_time_prism_adapt.cxx benchmark demonstrates adaptive mesh refinement (AMR) in time-prism domains, which are essential in simulations involving time-dependent partial differential equations.
This benchmark serves as a performance and correctness test for the library's AMR features.
| Option | Argument | Description |
|---|---|---|
| -h, --help | Display a short help message. | |
| -s, --slevel | INT | Initial refinement level. |
| -f, --flevel | INT | Final refinement level. Should be greater than or equal to initial refinement level. |
| -a, --adapt | INT (0/1) | Use adaptive refinement (1 = enabled, 0 = disabled). |
| -b, --balance | Establish a 2:1 balance in the forest (enforces mesh quality). | |
| -c, --cube | INT (0/1) | Use hypercube mesh and visual output (1 = enabled). |
| -e, --elements | INT | Type of elements: 5 = tetrahedra, 6 = prisms. |
mpirun -np 2 ./t8_time_prism_adapt -s 1 -f 3 -e 6 -a 1 -c 1
This command runs the benchmark with:
-
Prism elements (
-e 6) -
Adaptivity enabled (
-a 1) -
Hypercube mesh with visual output (
-c 1) - Initial refinement level set to 1 and final refinement level to 3
- Timing and correctness information for AMR operations.
- Visual output files (if
-c 1is set) for mesh visualization in tools like ParaView.
- Ensure that the element type (-e) matches your simulation setup (5 for tetrahedra, 6 for prisms).
- Use
