    Batch process / scheduling Nx

    Hello Community Is there way to batch process sim file one after other in SimCenter. I am frequently in situation where I have number of sim files which i would like to run over weekend mostly one job after other. Is there a way to do it? A scheduling tool would be great. Thanks and...

    How much momemt of Inertia will be felt at engine if we attach a disc of moment of inertia X?

    @jgKRI What if the disc is attached to the outputshaft of gearbox, and if you neglect moment of inertia of gearbox and engine? what will be the feeling of MOI due to Disc at Engine

    How much momemt of Inertia will be felt at engine if we attach a disc of moment of inertia X?

    How much momemt of Inertia will be felt at engine if we attach a disc of moment of inertia​ 0.4kgm²at end ? I would say Zero , because of no unbalance Mass on axis of rotation

    Pivot Element Error

    Update: I tried for isotropic material and i could solve by staic subcase but it fails for equivalent panel http://files.engineering.com/getfile.aspx?folder=8aa8a22a-1403-4f9a-a15f-b82431caa4a4&file=equisidefixrotstat.bdf

    Pivot Element Error

    Hello Group, I am trying to simulate simple bending of a hat-stiffened panel. I calculated A, B, D matrices with Equvivalent formulation as in Colliers Papers and used 3 MAT2 cards to define them. In P-shell element for equivalent formulation i referred the corresponding bending, coupling and...

    Criterion for Modell Validation/ callibration

    PS: I am validating the model in range 0 to 200 hz. Should I take the frequency values at resonance for validation with FDAC or any values at suitable interval will be good enough.

    Criterion for Modell Validation/ callibration

    Hello Greg I have have been going through some post and then some scientific papers. And i believe that FDAC is possible way for correlating and Model updating in my case. Reasons 1) It takes into account frequency shift 2)FRF can be directly used used for corelation without extracting modal...

    Criterion for Modell Validation/ callibration

    Hallo Group I am new to NVH simulation. I have a component tested for vibration. From the test involved measuring Frequency response function (Mobility)FRF on 6 points on the modell. So I have plots of FRF values at Six points on the modell. Using this I want to calibrate My FEM model (with...

    Damping in Durafoam Part- FEM (automotive \ structural)

    Hallo I have a automotive part made of DuraForm® HST Composite with rapid protoyping (SLS). I want to analyse this for natural frequency (NVH) with FEA software . Any idea suggestion how I include damping parameter (structural / material) in FEA Model. So any ques to any literature about it.
