Export of plies and laminates into Samcef zones (Simcenter Samcef)

To specify how you want laminates data to be written in the Simcenter Samcef input file, use the Global Ply Id or Local Ply Id output format options in the Laminate Modeler dialog box.

• The Local Ply Id and Global Ply Id options are available for 2D Laminate properties, but not for 3D Solid Laminate ones.

• The Global Ply Id option uses the Simcenter Samcef ZONE format of the .PLI and .LAM draping commands.For more information, see the 3-D Laminated structures modeling with zones chapter in the Simcenter Samcef Draping commands

Note:

You can improve your layup model by selecting the Account for Woven Fiber Shear option in the material dialog box. This option also impacts the way zones are created.

For more information, see Woven ply material in laminates zones (Simcenter Samcef).

Ply-based workflow with the Global Ply Id option

In the Ply-based workflow, Laminate Composites computes zones from the Global Layup data. The Global Ply Id option is the only option.

These Laminate Composites zones are output as Simcenter Samcef zones in the input file. Because the software computes zones, the same ply ID can spread over several zones but may have different properties (for example, material orientation) on each of these zones.

In this case, the Simcenter Samcef input file contains data as follows:

• Different Simcenter Samcef groups that collect the elements of the zone. .SEL GROUP "zone1" ELEMENTS I ... GROUP "zone2" ELEMENTS I ...

• The sample ply ID but with different properties on the different zones. .PLI  I 1 ANG 0.1... ZONE "zone1" I 2 ANG 0.2 .. ZONE "zone1" .PLI I 1 ANG 1.1... ZONE "zone2" I 2 ANG 1.2 .. ZONE "zone2"

• As many laminate definitions as exist in the different zones. .LAM  I 1 PLI 1 2 ZONE "zone1" I 2 PLI 1 2 ZONE "zone2"

• The draping .ETA command works on individual elements (of the different zones), not on the zones themselves. .ETA I ... LAM 1 PROJ DIR ... I ... LAM 2 PROJ DIR ...

Zone-based workflow with the Global Ply Id option

In the Zone-based workflow, you can use the Global Ply Id to create Simcenter Samcef zones in the input file.

The Simcenter Samcef zones match the Mesh Collectors. The advantage of the Global Ply Id option is that you can have the same ply id on different collectors that have different properties.

In this case, the Simcenter Samcef input file contains data as follows:

.SELGROUP "MeshCollector(1)" ELEMENTS I ...GROUP "MeshCollector(2)" ELEMENTS I ....PLII 1 ANG 0.1 ..... ZONE "MeshCollector(1)"I 2 ANG 0.2 ..... ZONE "MeshCollector(1)".PLII 1 ANG 1.1 ..... ZONE "MeshCollector(2)"......LAMI 1 PLI 1 2 ZONE "MeshCollector(1)"I 2 PLI 1   ZONE "MeshCollector(2)".ETAI ... LAM 1 PROJ DIR ...I ... LAM 2 PROJ DIR ...

Zone-based workflow with the Local Ply Id option

In the Zone-based workflow, if you use the Local Ply Id option, no Simcenter Samcef zone is created and the output is the same as that in Simcenter 3D version 12 or earlier.

In this case, the Simcenter Samcef input file contains data as follows:

.PLII 1 ANG 0.1 ..... I 2 ANG 0.2 ..... .PLI I 3 ANG 1.1 ..... .LAMI 1 PLI 1 2I 2 PLI 3.ETAI ... LAM 1 DIR ...I ... LAM 2 DIR ...

Note:

With the Local Ply Id option, you must ensure that the ply IDs are unique throughout your model.
