Samcef Interface

Overview of the Samcef interface.

The Samcef interface enables you to:
  • Use the Entity Editor for all entities created from the Model Browser
  • Specify linear analysis (module ASEF)
  • Specify a linear, nonlinear static analysis
  • Export a .dat file
  • Read and write a .dat file
  • Preview and edit Samcef cards
In addition:
  • Samcef .sdb files are not supported
  • Warnings and error messages are written to a file named samcef.msg. Unrecognized lines are written to a *.hmx file. These files are created in the same directory from where HyperMesh is launched.
The following commands are supported:
  • Nodes (.NOE)
  • Elements (.MAI, .MCE MEAN, .MCC MEAN, .MCE BUSH)
  • Property (.PHP, .BPR, .MCC BUSH)
  • Material (.MAT)
  • Loads (.CLM)
  • System (.FRA)
  • Output request (.SAI)
  • Hypothesis (.HYP)
  • Entity Set (.SEL NOE, .SEL MAI)
  • Contactsurfs (.SEL FACE)
  • Composite definition (.PLI, .LAM, .ETA)
  • Contact definition (.MCT, .STI)

Contact .MCT

Link between HyperMesh keywords and the Samcef contact .MCT parameters.

For a complete definition of the card .MCT, refer to the Samcef help.

Selection of “contact resolution method” [Option_number]
“Uncoupled“ (default)
Write OPT 3
“Coupled”
Write OPT 2.
“Sliding magnitude” [Contact_characteristics]. You can control this option by two choices:
« Moderate » (default)
Nothing is written on MCT Card.
« Large »
NLIM -1 must be written on the MCT definition
“Initial gap” Contact_characteristics. You can control this option by two choices:
“As mesh is” (default)
Nothing is written on the MCT definition.
“No initial gap”
UN3 1 must be written on the card definition.
“Contact offset” Contact_characteristics. You can control this option by two choices:
“As mesh is” (default)
Nothing is written on the MCT definition.
“Contact offset”
You must enter a value XX; DMIN XX must be written on the card definition.
“Kind of contact” Contact_characteristics. You can control this option by two choices:
“Standard” (default)
Nothing is written on the MCT definition.
“Normal direction glue”
OPCO 2 must be written on the card definition.
Selection of “Curvature smoothing contact faces” [Smoothing_characteristics]
“Non activated” (default)
Nothing is written by default on MCT card.
“Activated”
Write KSMO 1 on MCT card.
Selection of “Curvature smoothing contact faces” [Smoothing_characteristics]
“Non activated” (default)
Nothing is written by default on MCT card.
"Activated”
Write KSMO 1 on MCT card.
Blank text line Additionnal_user_text.

Enter free text on the current panel, on the Samcef MCT card. The text is saved with the contact definition in HyperMesh.

Examples:
  • .MCT I 10 GROUP 17 GTAR 23 OPT 3 ! Contact default
  • .MCT I 20 GROUP 65 GTAR 12 OPT 2 NLIM -1 UN3 1 DMIN -0.0245 KSMO 1 ! Advanced contact
  • .MCT I 30 GROUP 45 GTAR 75 OPT 2 UN3 1 OCPO 2 KSMO 1 ! Glue contact

Contact .STI

Link between HyperMesh keywords and the Samcef contact .STI parameters.

For a complete definition of the card .STI, refer to the Samcef help.

Selection of “Node project” [Option_number]
  • “Non activated“ by default ; write PROJ 0
  • “Activated”; nothing to write on STI card
Example:
  • .STI I 1 GROUP 17 23 PROJ 0 ! Glue default
  • .STI I 2 GROUP 35 64 ! Advanced glue
