Reply To: PSD (random vibration) and Acceleration on a body (harmonic response)

[AR]

Hi dlooman,

 

I just make a little model to try the code but it was impossible for me to do it work. 

 

In case of Harmonic Response, I use the CMACEL with a Named Selection that I made cald "NodosMotor". I also try it with a named selection of the body of the engine. However, in Solution Output I have a warning messages: There is no component named NODOSMOTOR in the model.  Please specify a valid component name to apply a translational acceleration (CMACEL command). The Harmonic Response solve but there are no results, as the acceleration were 0. 

In case of the Response Spectrum, I use "cmsel, s,NodosMotor,node" to select the nodes in that named selection before the "pfact,2,all", but I obtain an error: SELECT COMPONENT NODOSMOTOR

 *** ERROR ***                           CP =       0.234   TIME= 17:41:15
 Component NODOSMOTOR is not defined.

 

Could you help me with that?

 

Thank you very much!!

 

Regards,
