Hi,<\/p>\n

<\/p>\n

I’m trying to measure the displacement of a pilot node\/remote point<\/p>\n

<\/p>\n

the remote point is created as external point:<\/p>\n

<\/p>\n

<\/p>\n

Measure_Pilot=_npilot<\/p>\n

\n<\/p><\/blockquote>\n

<\/p>\n

\"\"<\/p>\n

<\/p>\n

I apply a displacement at the top of the beam and use the following APDL code to gather displacement and rotation of the pilot node:<\/p>\n

<\/p>\n

<\/p>\n

my_ux=UX(Measure_Pilot)<\/p>\n

<\/p>\n

my_uy=UY(Measure_Pilot)<\/p>\n

<\/p>\n

my_uz=UZ(Measure_Pilot)<\/p>\n

<\/p>\n

 <\/p>\n

<\/p>\n

my_rotx=ROTX(Measure_Pilot)*57.29577951<\/p>\n

<\/p>\n

my_roty=ROTY(Measure_Pilot)*57.29577951<\/p>\n

<\/p>\n

my_rotz=ROTZ(Measure_Pilot)*57.29577951<\/p>\n

\n<\/p><\/blockquote>\n

<\/p>\n

I have 3 steps and a time increment of 0,1s and tried to implemnt it in a loop to store the time dependant displacement in a txt file:<\/p>\n

<\/p>\n

<\/p>\n

total_time=1<\/p>\n

<\/p>\n

time_steps=3<\/p>\n

<\/p>\n

time_inc=0.1<\/p>\n

<\/p>\n

 <\/p>\n

<\/p>\n

*cfopen,Remote_Point_Data,txt<\/p>\n

<\/p>\n

*do,I,0,total_time,time_inc<\/p>\n

<\/p>\n

   my_ux=UX(Measure_Pilot)<\/p>\n

<\/p>\n

   my_uy=UY(Measure_Pilot)<\/p>\n

<\/p>\n

   my_uz=UZ(Measure_Pilot)<\/p>\n

<\/p>\n

   my_rotx=ROTX(Measure_Pilot)*57.29577951<\/p>\n

<\/p>\n

   my_roty=ROTY(Measure_Pilot)*57.29577951<\/p>\n

<\/p>\n

   my_rotz=ROTZ(Measure_Pilot)*57.29577951<\/p>\n

<\/p>\n

*vwrite,ux,uy,uz,rotx,roty,rotz<\/p>\n

<\/p>\n

(6F10.9)<\/p>\n

<\/p>\n

*enddo<\/p>\n

<\/p>\n

*CFCLOS<\/p>\n

\n<\/p><\/blockquote>\n

<\/p>\n

The txt stores only zeros, and the code for measuring displacement shows only the end result, not the time dependant behavior for every step.<\/p>\n

<\/p>\n

Has anyone a suggestion what is wrong with the APDL lines ?<\/p>\n

<\/p>\n

Best regards<\/p>\n
