Hi, I need to write my frequency response results (deformation, velocity, phase, for example) in a text file. I can write thew array for each substep and include the frequency of each substep and the displacement in the freuqency range. But I did not find how to include the respective velocity or the phase in the array. (I include the code I am using, which works).

*set,last

*get,freq_count,active,,set,sbst

*dim,freq_array,ARRAY,freq_count,2

*do,ii,1,freq_count     

   SET,1,ii    

   *GET,temp_b,ACTIVE,0,SET,FREQ             

   freq_array(ii,1)=temp_b       

   cmsel,s,MY_KEYPOINT   

   *get,node_id,NODE,0,num,max     

   *get,displ,NODE,node_id,U,sum     

   freq_array(ii,2)=displ

*enddo

 

*cfopen,'myharmonic','txt'

*vwrite,'Freq','displ'

(A8,X,A8)

*vwrite,freq_array(1,1),freq_array(1,2)

(F6.0,X,F10.2)

The velocity is simple. Multiply displacements with frequency array and time it with 2*pi. That is because velocity is angular frequency times displacement.

For the phase have a look at plcplx commands and search for examples.
