Hi, Just updated main CMake build; chrono::fsi::tdpf produced the following error.
==== Chrono FSI module ==== Generic Chrono::FSI interface library Add Chrono_fsi library SPH-based Chrono::FSI submodule Chrono CUDA architectures: all-major Use double precision? OFF Splashsurf NOT found. Surface reconstruction utility disabled. Add Chrono_fsisph library TDPF-based Chrono::FSI submodule CMake Warning at src/chrono_fsi/tdpf/CMakeLists.txt:25 (message): Required HDF5 support not available; disabling Chrono::FSI-TDPF 在2026年2月8日星期日 UTC+8 03:57:36<Zero> 写道： > For modeling ground/soil/rock, which modules should be used — chrono::dem > or chrono::fsi?
