Hi there - can you please describe what you try to accomplish? We might be able to help with the ANCF tire model, but before that, please tell us what you want to accomplish since there might be easier paths forward. ANCF is heavy duty.

From: projectchrono@googlegroups.com <projectchrono@googlegroups.com> On Behalf Of juju Sent: Thursday, July 31, 2025 11:41 AM To: ProjectChrono <projectchrono@googlegroups.com> Subject: [chrono] HMMWV with ANCF tire Good morning, I am a PhD student working on off-road vehicle navigation, and I found ProjectChrono very interesting for testing my algorithms. I would like to use the HMMWV vehicle with ANCF tires for more realistic behavior. However, when I run the demo script demo_VEH_SCMTerrain_WheeledVehicle.cpp with TireType::FEA, the simulation becomes unstable and extremely slow. It runs fine with other tire types. Does anyone have a demo script using HMMWV with ANCF tires that is both stable and performs well (accelerated and reliable)?
