How to GET mode shape vector from ANSYS APDL?

Hi,

You have to write macro for that.

After your solution

/POST1

ASEL,S,LOC,Y,0.085

NSLA,S,1

NPLOT ! select required nodes

*GET,a_count,NODE,1,COUNT !count of the selected nodes

set,last ! set pointer to last of the frequency count

*get,a_modecnt,active,,set,sbst ! get count of modes

*VGET,testarry,NODE,NoNodes,NLIST,,,, 4 ! get the node numbers of selected one in array

!defining nodal mask array to avoid repeated selection

*DIM,na_mask,ARRAY,a_count

*VGET,na_mask(1),NODE,1,NSEL ! create mask

!defining array for co-ordinates and vector data

*DIM,acoust_cord,ARRAY,a_count,(3+a_modecnt)

*DO,I,1,a_count

*VMASK,na_mask(1) ! Mask on selected nodes

*VGET,acoust_cord(I,1),NODE,testarry(I),LOC,X ! Get node x

*VMASK,na_mask(1)

*VGET,acoust_cord(I,2),NODE,testarry(I),LOC,Y ! Get node y

*VMASK,na_mask(1)

*VGET,acoust_cord(I,3),NODE,testarry(I),LOC,Z! Get node z

*DO,J,1,a_modecnt

SET,1,J ! Open the mode

*VMASK,na_mask(1)

*VGET,acoust_cord(I,3+J),NODE,testarry(I),PRES ! pressure data

*ENDDO

!!!! writting acoustic data

*CFOPEN,veena_a_0.03,csv

!*VMASK,na_mask(1)

*VWRITE,acoust_cord(1,1),acoust_cord(1,2),acoust_cord(1,3),acoust_cord(1,4),acoust_cord(1,5),acoust_cord(1,6),acoust_cord(1,7),acoust_cord(1,8)
