Advanced Drucker-Prager criterion for Explicit Analysis
Users can now input advanced Drucker-Prager properties such as Dilation Angle and Yield Curve Type, for Bi-Linear and Plastic nonlinear material when the active analysis type is set to Explicit.
- Dilation Angle has a default value set to 0 degrees and a maximum value of 71.5 degrees: i.e 0o ≤ Dilation Angle ≤ 71.5o.
- Yield Curve Type has three options in the drop down: Compression, Tension, and Shear. Compression is set as the default Yield Curve Type.
Inertia values in Automatic Concentrated Mass
The Inertia values in Automatic Concentrated Mass are populated automatically with the mass moment of inertia value (COG as the origin). Currently automatic concentrated mass is only supported for assembly (.iam) models.
This feature is very useful when running modal/dynamic analyses.
To create a new concentrated mass from the model tree:
- Select "Automatic" in the Type section.
- Select a body from the canvas.
- Input the density value.
Model state improvements
Changing model states with loads or constraints applied on modified geometric entities no longer gives the following error message: "Some features have been lost due to geometry modification".
The loads or constraints are properly retained.
Improved mid-side node recognition in continuous meshing
The mid-side node recognition for shell elements when continuous mesh is checked is improved, along with loads, constraints, and connectors recognition applied to the mid-side nodes.
