Hi Ruochun, Thank you and your team for your ongoing efforts. However, I regret to tell you that the DEM-engine based on CUDA 13.0 failed to compile on my end. The error messages are as follows: Total num of triangles: 320 Total num of particles: 200958 DEM/Defines.h(16): warning: cuda_runtime.h: [jitify] File not found CUDAMathHelpers.cuh(49): warning: cuda_runtime.h: [jitify] File not found DEMPrepForceKernels(5): warning: curand_kernel.h: [jitify] File not found DEM/Defines.h(16): warning: cuda_runtime.h: [jitify] File not found CUDAMathHelpers.cuh(49): warning: cuda_runtime.h: [jitify] File not found DEMBinSphereKernels(5): warning: curand_kernel.h: [jitify] File not found DEM/Defines.h(16): warning: cuda_runtime.h: [jitify] File not found CUDAMathHelpers.cuh(49): warning: cuda_runtime.h: [jitify] File not found DEMCalcForceKernels(6): warning: curand_kernel.h: [jitify] File not found DEM/Defines.h(16): warning: cuda_runtime.h: [jitify] File not found CUDAMathHelpers.cuh(49): warning: cuda_runtime.h: [jitify] File not found DEMContactKernels_SphereSphere(5): warning: curand_kernel.h: [jitify] File not found DEM/Defines.h(16): warning: cuda_runtime.h: [jitify] File not found CUDAMathHelpers.cuh(49): warning: cuda_runtime.h: [jitify] File not found DEMCollectForceKernels_Compact(5): warning: curand_kernel.h: [jitify] File not found DEM/Defines.h(16): warning: cuda_runtime.h: [jitify] File not found CUDAMathHelpers.cuh(49): warning: cuda_runtime.h: [jitify] File not found DEMBinTriangleKernels(6): warning: curand_kernel.h: [jitify] File not found CUDAMathHelpers.cuh(49): warning: cuda_runtime.h: [jitify] File not found DEM/Defines.h(16): warning: cuda_runtime.h: [jitify] File not found DEMIntegrationKernels(5): warning: curand_kernel.h: [jitify] File not found DEM/Defines.h(16): warning: cuda_runtime.h: [jitify] File not found CUDAMathHelpers.cuh(49): warning: cuda_runtime.h: [jitify] File not found DEMContactKernels_SphereTriangle(6): warning: curand_kernel.h: [jitify] File not found DEM/Defines.h(16): warning: cuda_runtime.h: [jitify] File not found CUDAMathHelpers.cuh(49): warning: cuda_runtime.h: [jitify] File not found DEM/Defines.h(16): warning: cuda_runtime.h: [jitify] File not found CUDAMathHelpers.cuh(49): warning: cuda_runtime.h: [jitify] File not found DEMHistoryMappingKernels(5): warning: curand_kernel.h: [jitify] File not found DEM/Defines.h(16): warning: cuda_runtime.h: [jitify] File not found CUDAMathHelpers.cuh(49): warning: cuda_runtime.h: [jitify] File not found DEMOwnerQueryKernels(5): warning: curand_kernel.h: [jitify] File not found Output at 10 FPS Frame: 0
