What GPU do you have? What is its architecture (computer capability)? Check the NVIDIA documentation. I think atomicAdd for float was only added in 8.0 or around that time. Is your GPU that old?

If you are interested in reviving it for your own use and assuming the SPH solver in the Chrono::FSI-SPH module cannot be used for your case, I can provide you information where we archived that capability. --Radu From: [email protected] <[email protected]> On Behalf Of Zero Sent: Thursday, May 7, 2026 2:14 PM To: ProjectChrono <[email protected]> Subject: [chrono] Does Chrono have an MPM algorithm?
