I have a cantilever beam and I want to drive a transient analysis. I used this code but the problem is ansys never end the calculation, is this code wrong or what?
/SOLU
ANTYPE,4
TRNOPT,FULL,,DAMP
LUMPM,0
OUTRES,ALL,ALL
DELTIM,Tres ! Specifies the time step sizes
TINTP,,0.25,0.5,0.5
!At the starting point
TIME,Tstep ! Sets time to Tstep seconds
F,350,FZ,frce
KBC,1 ! Ramped load step
SOLVE
FDELE,350,ALL ! Delete the load at the end
*GET,y,NODE,351,U,Z
y=y*1000
Hi, there isn't really enough information in your question to determine why the solution is not converging. I notice that you have used the OUTRES, ALL, ALL command. Are you getting any results written for substeps?
Hi, thanks for sending me the log file. I have a few questions:
1) It is not clear why you are not using beam elements as your model seems to consist entirely of flat beams. This is particularly an issue in relation to the way that you have applied the force - as you have applied it to a single node in the middle of a flat sheet, you are going to introduce a singularity here - using beam elements avoids this happening.
2) Have tried to solve the exact same model just as a simplified static analysis? In my experience if you are able to get this working correctly first then it is relatively easy to upgrade it to a transient analysis.
please could you resend me the code with your review to be able see what exacly you ask for
Hi - my advice to you would be to get a static analysis working first (i.e. without time). Once this is working OK then try and introduce the transient analysis.
