Chaining with a linear static solution (Simcenter Samcef)

You can chain a Linear Static active 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:Static pre-stress—Performs a Linear Static solution with pre-stress conditions.Static with centrifugal stiffness—Performs a Linear Static solution with centrifugal stiffness computation.Static with initial imperfection—Performs a Linear Static solution with initial imperfection condition.Chained thermal-structural analysis—Performs a classic Heat Transfer - Linear Static chaining.Chained thermal-structural analysis with dissimilar mesh—Performs a Linear Static 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.

Static pre-stress chaining type

The Static pre-stress chaining type chains two linear static analyses. In the active linear static solution, you select the previous linear solution's load case from which you want to retrieve the pre-stress data.

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 source for stresses. For more details, see the IFPR FILE parameters of the .SAM Samcef command.
Load Case Number	Lets you select the load case number from which you want to retrieve the stresses. 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 in the linear static solution and the load case you want to chain with.

Static with centrifugal stiffness chaining type

The Static with centrifugal stiffness chaining type chains two linear static analyses. In the active linear static solution, you select the previous linear solution's load case from which you want to retrieve the centrifugal stiffness.

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 source for the centrifugal stiffness. For more details, see the IFPR FILE parameters of the .SAM Samcef command.
Load Case Number	Lets you select the load case number from which you want to retrieve stiffness. 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 in the linear static solution and the load case you want to chain with.

Static with initial imperfection chaining type

The Static with initial imperfection chaining type chains a buckling analysis with a linear static one. The linear static active solution uses one of the computed buckling modes as the initial imperfection condition for the linear static solving.

Option	Description
Mode Shape Number	Lets you select the buckling mode to take into account in the chaining. For more details, see the NDEF parameter of the .SAM Samcef command.
Mode Shape Amplitude	Lets you define the mode shape amplitude to apply to this buckling mode. For more details, see the ADEF parameter of the .GEL Samcef command.
Chaining with Solution	Available when you select Solution from the Source Type list.Lets you select the buckling solution you want to chain with.
***_st.u18 File**	Available when you select External File from the Source Type list.Lets you select the Simcenter Samcef binary buckling results file to use as source. For more details, see the IFDEF FILE parameters of the .SAM Samcef command.

Chained thermal-structural analysis chaining type

The Chained thermal-structural analysis chaining type chains a thermal analysis with a static linear one. In the active linear static solution, you select the reference time at which the nodal temperatures must be retrieved 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 given 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 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 linear static one. In the active linear static solution, you select the reference time at which the nodal temperatures (or the degree of cure values or the glass transition temperatures) have to be retrieved 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.
