Hello everyone,
I wrote some user elements. Those were working fine with feappv, but now I am using those element routines with feap 8.6, then it's not working.
Could someone please help me with this? What are the changes I need to make?
Thank you
Regards

Post one of the elements
-
missing routines iom_delta , iom_det , iom_invert
-
All these routines i copied in program folder of feap 8.6 .
-
They are your routines, I cannot check your element without them.
In general it is not good practice to add things like this to the main program but keep separate in your modules.
-
I do not see any obvious reason element should not work in ver8.6.
Can you describe what happens?
Do all routines compile?
Are all inputs acknowledged in the output file?
I would suggest you run the problem in interactive mode.
Use commands like: EPRInt to see the element stiffness produced.
Give one TANG to see what happens.
You may need to use a debugger to find what is the problem.
-
Feappv solving the problem whereas feap 8.6 not solving the problem. (please check the attachment for the output files of the above-attached input file from both versions )
Yes, I compile all the programs.
please have look at the output files.(attached)
thank you

The only error I see is the lack of setting "pstyp = 3" under isw.eq.1
You do not set the "inord" array in feap -- instead you tell the program that elements are 3-d solides using the pstyp parameter. Since you have NOPRINT you do not see anything.
It runs on my computer and says it converged but I do not know if the answers are correct.
