Thanks for the material

How about post processing steps do you have documentation what will be output and how to process for the same example

Thanks for your help in advance

Please refer below HyperWorks Insider link for Transfer Path Analysis. This is a bit of old material but worth reading.

Hi @Rahul R 

From the demo file i got the Response and  Path contribution as mentioned in the tutorial. If i need the Input Force, Transfer Function and Point of Mobility means i need to request GPFORCE or SPCFORCE for the connection points right. 

If i request that GPFORCE means i getting an error

  *** ERROR # 2869 ***
 The grid 1130488 associated with component 1 does not have any reaction
 forces. It is likely that the element set (CONEL) or RIGID set (CONREL)
 specified in PFPATH does not contribute any reaction force to this
 degree of freedom.

How to extract the Input force, transfer function and Point of Mobility results??

GPFORCE is not necessary for one step TPA, and pfpath can deal with this internally. In HyperView ,ensure that the NVH Utilities are loaded from the Preferences menu.This should help you to get the Input Force, Transfer Function and Point Mobility. PFA material for post processing using NVH utilities.

Thanks @Rahul R

This is fine at particular frequency  we are getting the magnitude of Transfer Function, Input force and Point of mobility. But if we need a Transfer Function for all over frequency for each node with the each direction as we get in Two Step TPA. is that possible in One Step TPA ??

Hi @Rahul R

I am not able to extract the Magnitude of Transfer Function and input force in one step TPA as shown in image. please check the file.

Can you share the One step TPA Result file and which result file format will support the One step TPA

Hi @Rahul R

why this error is coming can please check it 

Hello,

@Shri. I am also working on the transfer function. I am also getting same error, i.e 'expected floating-point number but got'. 

Did you find the solution? Please help me with it.

Hi All, 

I am trying to learn TPA analysis in NVH 

Kindly someone help with reference deck and document about background process and post processing. I have tried to download attachments but either it's removed or not available. Please do the needful. Or else any one please share me on my mail-ssadhikari01@gmail.com. Your help will be highly appreciated.. 

Thanks in advance
