Best practices to improve stability on scFLOW side?

Oscar Lorenzo Rodriguez

Hello everyone,

When dealing with challenging Marc - scFLOW analysis and encountering stability issues on the CFD side, are there any good practices to follow to improve the robustness of the simulation in scFLOW side?

    When dealing with FSI and associated mesh deformation, this could lead to unwanted low-quality mesh elements, depending on the mesh deformation algorithm used (Harmonic, LDC, or RBF).
    The scFLOW Log file is the first file to be analysed to see if there is

    •  negative mesh element appears
    • sufficient loop number to converge between physical time steps
    • courant number no too big to be computed in a stable way
