Serenity is a parallel, low-frequency (exact or full wave) radar cross section (RCS) and signature prediction code that uses the three-dimensional Method of Moments (MoM). It is intended for treating objects of intermediate to large electrical size that asymptotic codes such as lucernhammer MT are ill-suited to handle.

Serenity is a state of the art moment method code, which fills and factors the MoM matrix directly in compressed form using the Adapative Cross Approximation (ACA) or Multi-Level Adaptive Cross Approximation (MLACA).

• Efficient Solution of Electromagnetic Scattering Problems Using Multilevel Adaptive Cross Approximation (MLACA) and LU Factorization

Feature Details

• Monostatic and Bistatic complex-valued scattered far field and RCS.

• Uses ACAD facet files, and uses RWG basis functions.

• Serenity uses the Adaptive Cross Approximation (ACA), which performs a direct block-LU factorization of the matrix in compressed form, and solves multiple right-hand sides simultaneously. Memory savings and solution speed are orders of magnitude better than a direct, full matrix solver. Both single and multi-level ACA (MLACA) are supported.
  • A short briefing outlining the capabilities Serenity ACA solver.
  
  
• Supports conducting (PEC) objects, as well as objects that are conducting, dielectric, or composite. Dielectrics may be lossy, and junctions between dielectric and conducting regions are fully supported.

• Supports multiple run-time geometry files, allowing the user to specify separately the pieces of a composite geometry or scene.

• An ultra-high performance GPU-accelerated single and multi-level ACA solver is available for systems with NVIDIA CUDA capable GPUs. Single and multi-GPU systems are supported.

• Highly parallelized, Serenity is available for shared memory (SMP) as well as distributed memory systems (clusters) using MPI. CPU-only clusters, or clusters where each node is equipped with one or more NVIDIA CUDA capable GPUs, are supported.

• The ACA solver supports out-of-core (OOC) operation for use with large, fast solid state disks (SSDs).

• Serenity is a console based application, and can be easily run inside scripts and batch jobs.
