Hi jamesdean2,
thanks for the response, I really appreciate it as it's hard to find any kind of information regarding this topic online.
I'm delivering the CLA package to Arianespace. The usual delivery consists of:
- separate op4 files with AC01, DP01, LTM1, LTM2, stiffness and mass matrices...
Hi,
I was assigned with a task to prepare a FEM for a CLA analysis (coupled loads analysis). The process should consist of standard nastran superelement reduction resulting in OP4/PCH/ASM file.
I should deliver the matrices separated (stiffness, mass, OTM forces, OTM accelerations, OTM...
I'm preparing a reduced model of my FEM for a Coupled load analysis (CLA). I need to deliver the following matrices:
KXX - stiffness matrix
MXX - mass matrix
AC01 - acceleration OTM matrix
DP01 - displacement OTM matrix
LTM - load OTM matrix
I'm using Femap with Simcenter Nastran as a solver...
Hi,
I'm using Femap as a preprocessor for Nastran solver. I want to reduce a portion of my model to a superelement and then use it in a subsequent analysis.
I'm using these options for Craigh-Bampton reduction...
