Remarks
The geometry definitions of CS elements resemble those of CP elements (e.g., CP3, CP4, CP5, CP6, CP7, CP8).
The characteristic length
[5]
can be left as default value (negative) to automatically determine the value based on geometry (square root of area), or set to a positive value to manually specify the fixed length.Currently, only supports
Elastic2D
.
