Families of results in structural and thermal output requests (Simcenter Samcef)

In the Simcenter Samcef Structural and Thermal analyses, when you select a result to output, you select a set of families of Simcenter Samcef code IDs.

For instance, in a Linear Static analysis, the Stress Tensor result is defined in the Simcenter Samcef documentation as:

Physical Quantity	Volumes	Shells (med/up/low)	Beams	Rods
Stress Tensor	x411	x431, x435, x436	-	-

By default, the Stress Tensor result outputs the following Simcenter Samcef codes:

• Results codes 1411 and 3411 on solid elements. The 3411 and 1411 codes are the Element and the Element-nodal versions of the same result on solids: the x411 stress tensor family.

• Results codes 1431, 3431 codes on midsurface of shells, 1435, 3435 codes on upper skin of shells, and 1436, 3436 codes on lower skin on shells. For instance, the 3435 and 1435 codes are the Element and the Element-nodal versions of the same result on upper skins of shells: the x435 stress tensor family.

By default, all the codes of all the families of a given result are output as .SAI ARCHIVE STRUCTURE STYP entries in the solver input file, where represents the entire set of codes for the specified result.

For instance, for our linear Stress Tensor example, a default .SAI ARCHIVE STRUCTURE STYP 1411 3411 1431 3431 1435 3435 1436 3436 entry is output in the Simcenter Samcef input file.

With the Location and the Type lists of the Output Requests modeling objects, you can reduce the list of codes to output.

Type of results

With the Type (1), you can select (2) to output the Elemental, the Element Nodal, or both versions of a same result:

Element

Only select the element version of the result.

Element Nodal

Only select the element-nodal version of the result.

All

Select both versions

Location of results (shells)

With the Location list (1), you can choose (2) between the Midplane, the Lower Skin, the Upper Skin, or All the positions in shells elements:

Lower Skin

Only select the lower skin version of the result.

Upper Skin

Only select the upper skin version of the result.

Midplane

Only select the midplane version of the result.

All

Select all the positions in the shell.

Critical Values for composite criteria

With the Critical Values (1), you can choose to add critical data output for the given result. You can add the result for theCritical Ply, you can add the Critical Ply Id number result, you can add them All, or you can exclude all these critical outputs (None).

Target elements (Entity)

Depending on the selected result, you can use the Entity list to output the result for the whole Structure or for a Group of elements/nodes.

Examples

The following examples shows how the combination of the list options described above can reduce the list of output results.

Example 1: Cauchy Stress Tensor result of a Nonlinear analysis

In the Simcenter Samcef documentation, the Cauchy Stress Tensor is defined as:

Physical Quantity	Volumes	Shells (med/up/low)	Beams	Rods
Cauchy Stress Tensor	x442	x448 / x478 / x408	-	x442

We have the following families:

• For volumes and rods: the x442 family.

• For shells: the x448, x478, and x408 families.

Examples combinations of results options:

Type list	Location list	Selected Entity	Output list of codes	Simcenter Samcef computed results	Explanation
All	All	Structure	.SAI ARCHIVE STRUCTURE STYP 1442 3442 1448 3448 1478 3478 1408 3408	Volumes and rods: 1442, 3442Shells: 1448, 3448 for midplane, 1478, 3478 for upper skins and 1408, 3408 for lower skinsBeams:-	All the Element and Element-nodal types are output.All the locations in shells are selected.The Cauchy Stress Tensor result does not exist for beams.From the output list, Simcenter Samcef attaches the right results codes to the right types of elements.
All	Lower Skin	Structure	.SAI ARCHIVE STRUCTURE STYP 1442 3442 1408 3408	Volumes and rods: 1442, 3442Shells: 1408, 3408Beams:-	The shells list of results is reduced to the Lower Skin counterpart.
Element	All	Structure	.SAI ARCHIVE STRUCTURE STYP 3442 3448 3478 3408	Volumes and rods: 3442Shells: 3448 for midplane, 3478 for upper skins and, 3408 for lower skinsBeams:-	Only the Element version of the results are output.
Element	All	A group of shells elements	.SAI ARCHIVE GROUP - STYP 3442 3448 3478 3408	Volumes and rods:-Shells: 3448 for midplane, 3478 for upper skins and, 3408 for lower skinsBeams:-	Simcenter Samcef only outputs shell results.

Example 2: Tsai-Hill 1 Criteria result of a Nonlinear analysis

In the Simcenter Samcef documentation, the Tsai-Hill 1 Criteria is defined as:

Physical Quantity	Volumes	Shells (med/up/low)	Beams	Rods
Tsai-Hill 1 Criteria	x621	x621 / 2x621 / 1x621	-	-

For this result, if we select the whole model (Structure) from the Entity list, we can have combinations like:

Type list	Location list	Critical Values list	Output list of codes	Simcenter Samcef computed results	Explanation
Element	All	None	.SAI ARCHIVE STRUCTURE STYP 3621 23621 13621	Volumes: 3621Shells: 3621 for midplane, 23621 for upper skins and, 13621 for lower skins	Only the element-based criteria results are output.
Element	All	All	.SAI ARCHIVE STRUCTURE STYP 3621 23621 13621 7621 8621	Same list as above plus:7621 8621	Critical ply values and the critical ply ID are added to the output list.The critical ply result (7621) is not separately output for the lower, upper, or midplane of the shells. Only the worst location is output.
