OrcaSPH - SPH Fluid Simulator with OrcaLink Integration
Project description
OrcaSPH - SPH Fluid Simulator with OrcaLink Integration
OrcaSPH 是一个 Python 包,提供 SPHSimulator 可执行程序和相关的库文件,支持通过 pip install orca-sph 安装,使用 orcasph 命令运行。
OrcaSPH 基于 SPlisHSPlasH 流体仿真引擎,集成了 Orca 系统的两个核心功能模块:
- OrcaLink:支持 SPH 仿真器与 OrcaLink 服务器的 gRPC 通信,实现流体对刚体的作用力传输和刚体位置/速度接收
- ParticleRender:支持粒子数据通过 gRPC 实时传输到渲染服务
Orca 集成允许在分布式系统中运行 SPlisHSPlasH 模拟器,并与其他计算节点进行实时数据交换。
系统要求
- Python:3.10+ (不再支持 3.8 和 3.9)
- 操作系统:Linux (x86_64)
- 系统库:已安装必要的系统库(libGL, libX11 等)
安装
从 PyPI 安装(推荐)
pip install orca-sph
安装后可以使用:
- 命令行工具:
orcasph --help - Python 模块:
import orcasph_client
基本用法
启动仿真
orcasph --scene path/to/scene.json
常用选项
使用 orcasph --help 查看完整的命令行选项,包括:
--scene FILE:场景文件路径(必需)--cpu RANGE:指定 CPU 核心范围--threads N:指定 OpenMP 线程数--config FILE:gRPC 配置文件路径--gui:启用 GUI 模式运行
