Chaining with a buckling solution (Simcenter Samcef)

You can chain an active Buckling solution with several other solved solutions. In the solution's Chaining page, you select the solved solution you want to chain with and define the chaining parameters.

Option	Description
Activate Chaining	Activates chaining.
Chaining Type	Specifies the chaining type:Stability Analysis non-proportional loading—Performs a Buckling Analysis after a static linear solution.Chained thermal-structural analysis—Performs a classic Heat Transfer - Buckling chaining.Chained thermal-structural analysis with dissimilar mesh—Performs a Buckling solution after a Mapping solution.
Source Type	Lets you select a Solution already defined in the current model to chain with or an External File Simcenter Samcef binary file (.u18) to extract chaining data from.

Stability Analysis non-proportional loading chaining type

The Stability Analysis on a proportional loading chaining type chains a buckling solution with a linear static one. In the active buckling solution, you select the previous linear solution's load case that you want to use as a pre-stress load case. No buckling load will be associated to this load case.

Option	Description
***_as.u18 File**	Available when you select External File from the Source Type list.Lets you select the Simcenter Samcef binary linear static results file to use as the source. For more details, see the IFPR FILE parameters of the .SAM Samcef command.
Load Case Number	Lets you select the load case number in the linear static solution that will act as a pre-stress load case. For more details, see the NPR parameter of the .SAM Samcef command.
Chaining with Solution	Available when you select Solution from the Source Type list.Lets you select the linear static solution and the load case you want to chain with.

Note:

If the model you chain with contains bolt preloads, you must ensure that these preloads are well taken into account. For more information, see Bolt conditions when chaining solutions (Simcenter Samcef).

Chained thermal-structural analysis chaining type

The Chained thermal-structural analysis chaining type chains a thermal analysis with a standalone buckling one. In the active standalone buckling solution, you select the reference time at which you want to retrieve the nodal temperatures from the thermal solution. These temperatures become thermal loads.

Option	Description
Selected Time	Lets you select the time at which you want to retrieve the thermal results. For more details, see the TIME parameter of the .GEL Samcef command.Note: The real time from which thermal results are retrieved is the thermal computing (and archiving) time which is the nearest to the specified Selected Time.
Chaining with Solution	Available when you select Solution from the Source Type list.Lets you select the thermal solution you want to chain with.
***_mt.u18 File**	Available when you select External File from the Source Type list.Lets you select the Simcenter Samcef binary thermal results file to use as the source. For more details, see the IUN FILE parameters of the .SAM Samcef command.

Chained thermal-structural analysis with dissimilar mesh chaining type

The Chained thermal-structural analysis with dissimilar mesh chaining type chains a mapping solution with a standalone buckling one. In the active standalone buckling solution, you select the reference time at which you want to retrieve the nodal temperatures (and the degree of cure and the glass transition temperatures if any) from the thermal solution. These results become thermal loads.

Option	Description
Selected Time	Lets you select the time at which you want to retrieve the thermal results. For more details, see the TIME parameter of the .GEL Samcef command.Note: The real time from which thermal results are retrieved is the thermal computing (and archiving) time which is the nearest to the given Selected Time.
Chaining with Solution	Available when you select Solution from the Source Type list.Lets you select the mapping solution you want to chain with.
***.txt File**	Available when you select External File from the Source Type list.Lets you select the mapping results text file to use as source.
