Failure in first example
Failure in first example
(OP)
hi all,
I`m new to use patran and I can not obtain a result in my first example.
Analysis Manager gives a failure and when I look in to stderr file, I read:
-------------------------------------------------
*** SYSTEM INFORMATION MESSAGE (pgm: nastan, fn: estimate_job_requirements)
Starting ESTIMATE, please wait...
*** USER INFORMATION MESSAGE (pgm: nastran, fn:estimate_job_requirements)
Estimated DOF=23070
Estimated memory=32.0MB
Estimated disc=163.4MB
Note: ESTIMATE had some difficulty analyzing this job.
---------------------------------------------------------
what can I do to obtaion solution or what is my mistake?
Thanks in advance

RE: Failure in first example
Look in the analysis directory for the *.F06 and open it with a text editor.
then look for "fatal" inside the *.F06.
Post here the fatal message and we will see what happen.

only *.bdf , *.db.jou , *.mon , *.stderr , *.stdout ,and *.tml
Thanks
RE: Failure in first example
could you run Nastran from outside patran and point the *.bdf file?
or could you post your *.bdf file here? In way that we can open and see if there is a problem?
RE: Failure in first example
I`m sending it.

RE: Failure in first example
In any case your model isn't well constrained and cannot run.
on my F06 I have the following:
^^^ USER FATAL MESSAGE 9050 (SEKRRS)
^^^ RUN TERMINATED DUE TO EXCESSIVE PIVOT RATIOS IN MATRIX KLL.
^^^ USER ACTION: CONSTRAIN MECHANISMS WITH SPCI OR SUPORTI ENTRIES OR SPECIFY PARAM,BAILOUT,-1 TO
CONTINUE THE RUN WITH MECHANISMS.
You should re evaluate yours constraints.

RE: Failure in first example
you can't run without constrain!!

RE: Failure in first example
but why didn`t I get *.F06 file?
and I tried it with nastran but nothing is happend
Actually I don`t know how can I run nastran.
I run nast2005.exe and then select input file and then nothing
thanks
RE: Failure in first example
If you run nastran 2005 be sure to have the patch for that version. after 1 april 2009 all version of nastran from 2005 and older need a patch. contact your msc reseller.
look at this thread: http://www
If you run directly nastran and nothing happen; and in the log file you have this message:
NSINIT: *** NSINIT ERROR 70 *** UNABLE TO OPEN UNIT 8
you need the patch.

RE: Failure in first example
I looked log file and i atteched the patch.
Now I get the solution.
RE: Failure in first example
Now you have to constrain the model with some SPC!!
