Rebeca, This error suggests that you either have a very old GPU (which is unlikely, as atomicAdd for double is available on devices with compute capability 6 and newer) or not really using CUDA 12.9 or 13.0 (but rather still 12.3).
You seem to have multiple versions of CUDA installed on your machine. How do you specify which one to use when you configure Chrono with CMake? Could you please post the CMake messages during Chrono configuration that indicate which version of CUDA was found and will be used? Something like the following: Searching for CUDA CUDA compiler: C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v12.8/bin/nvcc.exe CUDA toolkit version: 12.8.61 CUDA toolkit root dir: C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v12.8 CUDA archs (from cache): all-major CUDA found and enabled.

Thank you for the suggestion, Dan! I will definetely try out PyChrono. I need to present a proof of concept to my undergrad thesis advisor in the next weeks so I had decided to go with C++ since I struggled a bit with Anaconda. But I'll try again :) Radu, I've been using the latest version, I downloaded it from the git. I'm able to compile and build Chrono and run Vehicle module projects. The FSI single wheel demo that comes in the pre compiled pack works just fine in my computer. But whenever I try to compile a new project, even the demo cpp itself, it will run and then simply close the prompt before the visual interface ever starts. This has been happening with CUDA 12.3, CUDA 12.9, CUDA 13.0. What baffles me is the fact I'm able to run the pre compiled exe, so it doesn't seem to be a hardware incompatibility. I really have no idea what's going on :( Have any of you ever faced a similar problem, where the prompt closes right at the FSI Initialize() line?

Older releases will obviously not work with new CUDA releases. The current Chrono code in the main branch of the repository should work fine with any new CUDA 12.* versions (e.g. 12.8 or 12.9), as well as CUDA 13.0 (although I only tested the latter on Linux). Any of these CUDA versions will work fine with the latest VS versions. Please make sure that: * you use the latest Chrono code from the development branch (‘main’). * Update your copy of Visual Studio to the latest version. * You can test with CUDA 13.0.1. If that doesn’t work, please let me know. But if you can install a different version of CUDA, I suggest you use 12.9 which is what I currently use on my Windows machine. --Radu From: [email protected]<mailto:[email protected]> <[email protected]<mailto:[email protected]>> On Behalf Of Rebeca Guimarães Sent: Thursday, September 18, 2025 10:45 PM To: ProjectChrono <[email protected]<mailto:[email protected]>> Subject: [chrono] FSI won't work Good afternoon! I've donwloaded and compiled Chrono and been able to run many projects. Since I'm running terramechanics analysis, I am now trying to run FSI SPH. I was able to code, configure and geenrate, but when I run the exe, it will halt at the Initialize and close the cmd. I think I've narrowed the issue down to CUDA. I'm using version 13.0.1. I read at the website I need to use 12.3, but my MSVC says it expects version 12.4 or newer. Can someone help me how to downgrade my MSVC so it will accept 12.3? Thanks!
