Hi, 

I have a Harmonic Response analysis with N frequencies. I want to create  an APDL macro that plots Stress Components and includes the "Sweeping Angle" every 45 degrees. 

I have figured out how to access the frequencies but have a hard time with the angle. Could you recommend any sources where I could find it? 

 

Thx

Hi

Can you explain a bit more (say your are in Mechanical workbench, and want to do what or), say are you using MAPDL or Mechanical etc.?

The more info. provided, the more and better feedback can be given by forum members. 

All the best

Erik

• I'm using Mechanical WB 2020R2, Harmonic Response Analysis
• I'd like to plot von-Mises Stress components over Sweeping Phase (0-135, every 45 deg) for each one of the frequencies of the system (using MAPDL not the GUI)

Generally, I'd like to find out how to access this "Sweeping Phase" option in APDL.

In mapdl we get real and imaginary part of a harmonic solution/result, or amplitude and phase (we set that with SET command) so there is no similar (sweeping phase) option in MAPDL.

In mapdl a macro is used for plotting called anharm.mac – very complex but you can have a look at it.

If this or macro does not help then open up a support request with the channel partner or with Ansys support, and we will try and help you (find a workaround etc.)

All the best

I think I found it:

HRCPLX

HRCPLX, LOADSTEP, SUBSTEP, OMEGAT, 1STLCASE, 2NDLCASE
Computes and stores in the database the time-harmonic solution at a prescribed phase angle.

 

Thanks!

That is great.

 

Closing as others might have a similar question.
