Comments

  1. The time step for thick-shell elements (defined with property /PROP/TYPE20, /PROP/TYPE21 or /PROPTYPE22) is computed from the in-plane surface. The thickness is not used for the time step computation.
  2. To be able to use this option, all the nodes of the single element facet through thickness should be connected to either thick-shell or solid element. The option is automatically deactivated in case the connectivity rule is not respected.
  3. This option is compatible with constant nodal time step (/DT/NODA/CST).
  4. This option is not compatible with Advanced Mass Scaling (/DT/AMS) and Implicit Analysis (/IMPL/…).
