    Question about "The ratio of deformation speed to wave speed exceeds 1.000"

    Hi all, I have a theoretical question about the error in Abaqus "The ratio of deformation speed to wave speed exceeds 1.000 in more than one element". Take a second look at this message I found it no difference from the error "# elements were distorted excessively." Because they both indicates...

    Defining ALE Adpative Mesh Domain for crash simulation

    Hi everyone! I'm using linear tet element for a car shape solid to simulate front impact in Abaqus/Explicit. I have defined velocity using "predefined field" in both "initial" and "dynamic, explicit" step. Then in the dynamic step I added gravity load, "frictionless" contact between the road and...
