Hi,Radu
Thanks for your reply, I found the multicore module. The Demo ran successfully, but I still have to install the OpengGL module for visualization, as per this page https://api.projectchrono.org/module_opengl_installation.html to install opengl,after clicking builtsl.bat, in my C:\Packages\gl directory only the include file is generated, and there is no lib folder as described in the documentation CMake Error at D:/CMake/cmake-3.27.6-windows-x86_64/share/cmake-3.27/Modules/FindPackageHandleStandardArgs.cmake:230 (message): Could NOT find GLEW (missing: GLEW_INCLUDE_DIRS GLEW_LIBRARIES) Call Stack (most recent call first): D:/CMake/cmake-3.27.6-windows-x86_64/share/cmake-3.27/Modules/FindPackageHandleStandardArgs.cmake:600 (_FPHSA_FAILURE_MESSAGE) D:/CMake/cmake-3.27.6-windows-x86_64/share/cmake-3.27/Modules/FindGLEW.cmake:238 (find_package_handle_standard_args) src/chrono_opengl/CMakeLists.txt:42 (find_package) I need your help 在2023年10月11日星期三 UTC+8 13:45:21<Radu Serban> 写道： > The “parallel” module was renamed (a long time ago) to the “multicore” > module.
