Reply To: Errors in grid refinement example cases in openlb-1.8.0

Thank you for quick replying.

I’m doubting the compiler, but I cannot reach the solution.

The configuration file is

CXX             := g++
CC              := gcc
CXXFLAGS        := -O3 -Wall -march=native -mtune=native
CXXFLAGS        += -std=c++20
# add CUDA include path and library path
CXXFLAGS        += -I/usr/local/cuda/include -L/usr/local/cuda/lib64

PARALLEL_MODE   := NONE

PLATFORMS       := CPU_SISD GPU_CUDA

CUDA_CXX        := nvcc
# Adjust to CUDA / driver library path so that CXX can resolve libcuda, libcudart and libcudadevrt
CUDA_LDFLAGS    := -L/usr/local/cuda/lib64
# for e.g. RTX 30* (Ampere), see table in <code>rules.mk</code> for other options
CUDA_ARCH       := 61

FLOATING_POINT_TYPE        := double

USE_EMBEDDED_DEPENDENCIES := ON

It works for openlb-1.7.

The below is the current environments.
Ubuntu 22.04
CUDA Version is 12.2
gcc version is 11.4.0

If you need any other details, please let me know!
